Though language manifests linearly, one word at a time, children must learn that words are embedded in constituents, which are in turn embedded in larger constituents. That is, they must learn that syntax is hierarchically structured. Prosody—speech melody and rhythm—is likewise hierarchically organized, with smaller prosodic constituents embedded in larger ones. This paper presents results showing that 20‐month‐olds (= 40) can use modifier + clause prosody to learn constituents at multiple levels in a hierarchically structured artificial grammar, but that they fail to learn from clause + modifier prosody. We consider several explanations for this asymmetry, and suggest that it may be due to the frequency of the two constructions in the input. Two parallel experiments with adults suggest that older learners may not be able to learn the prosodically marked constituents. Instead, adult responses are likely based on perceptually prominent boundary words.  相似文献

This article deconstructs the “illegal–legal” binary that characterizes much immigration scholarship. Using in‐depth interviews with 42 1.5‐generation Brazilian immigrants in young adulthood, I find that respondents discuss a distinct hierarchy with four categories of legal membership—undocumented, liminal legality, lawful permanent resident (LPR), and citizen—that affect their daily lives and incorporation. Liminally legal and LPR statuses in particular challenge this illegal–legal dichotomy. Liminal legality is an “in‐between” status in which immigrants possess social security numbers and work permits but have no guarantee of eventual citizenship. Without opportunities to regularize their status, both undocumented and liminally legal young adults face increased vulnerabilities to poverty and social exclusion. Liminally legal youth, however, are in better positions than their undocumented peers during early adulthood because of state‐delimited rights associated with their legal status.  相似文献

Statistical inferences for the geometric process (GP) are derived when the distribution of the first occurrence time is assumed to be inverse Gaussian (IG). An α-series process, as a possible alternative to the GP, is introduced since the GP is sometimes inappropriate to apply some reliability and scheduling problems. In this study, statistical inference problem for the α-series process is considered where the distribution of first occurrence time is IG. The estimators of the parameters α, μ, and σ2 are obtained by using the maximum likelihood (ML) method. Asymptotic distributions and consistency properties of the ML estimators are derived. In order to compare the efficiencies of the ML estimators with the widely used nonparametric modified moment (MM) estimators, Monte Carlo simulations are performed. The results showed that the ML estimators are more efficient than the MM estimators. Moreover, two real life datasets are given for application purposes.  相似文献

Urban development has profound impacts on ecological patterns and processes making the scientific information required for developing environmental ordinances central for mitigating these negative ecological impacts. Washington State requires that planners use the best available science (BAS) to formulate land use ordinances as part of the state’s Growth Management Act (GMA). We present empirical findings describing challenges to planners in defining “best available science” and using BAS to create local ordinances that balance development needs with natural resource protection. We interviewed city and county planners (and their consultants) in western Washington to determine what they find useful about BAS, whether or not BAS is applicable to their jurisdictions, and what constraints they experience in reviewing and using BAS to create or update their land use ordinances. Our results suggest that applying the BAS requirement is particularly difficult in urban areas. Specifically, planners had difficulty applying results from research conducted in systems dissimilar to their urban landscapes. These challenges to planners were exacerbated by (1) a lack of resources and (2) political tensions among stakeholders with competing values in urban settings. We conclude with recommendations for improving the consideration of science in statewide land-use planning.  相似文献

Adaptation of agricultural and industrial research and development models offers new methods for bridging the worlds of research and practice in child and youth services. Social R & D methodologies provide effective means for generating new social technologies because they are product oriented and use a wide array of traditional and nontraditional data sources. This article discusses one social R & D paradigm—Developmental Research and Utilization. Permanency planning and community support systems research are used to illustrate the past and potential application of this methodology to the field of child and youth services.  相似文献

Because of the high chronicity of work-related problems in a Veterans Administration Medical Center population, many of the traditional methods of career assessment, counseling, and placement have proven ineffectual. In this article the authors detail the development of an intervention based on narrative or storytelling principles. They describe efforts to introduce this model to patients as well as to relate patients' stories to vocational outcomes. The usefulness of stories as an organizing principle for counselors and clients is discussed, and suggestions are offered for further uses of storytelling interventions.  相似文献

Using data from in-depth interviews with 115 women, men and couples in eastern Australia for whom family formation was a recent, current or imminent future issue, this article explores contemporary childlessness among those physically able to have children. It differentiates between those childless by choice and by circumstance, and among other themes highlights (i) the role preservation of lifestyle appears to play as a motive for deliberate childlessness following development of a life course through early adulthood that both generates lifestyle aspirations and often places parenthood on the backburner until after age 30, and (ii) the roles difficulty forming suitable relationships, women’s desire for meaningful careers, and male involvement in family formation decisions play in bringing about childlessness by circumstance.  相似文献

This discussion paper will examine the lessons from the Munro Review relevant for looked after children. Although the Munro Review focuses on child protection, we will argue that some of its key principles have relevance for understanding looked after childhoods. The Munro Review provides an analysis of the current state of the child protection system, challenging bureaucratised practice and arguing for a reclaiming of professional social work identity, knowledge and understanding. There are three key principles of the Munro Review that this paper will focus upon. The first two are the recognition that risk cannot be eradicated and the bureaucratisation of practice is an inadequate response to the demand for public accountability. The third principle is that ethical integrity lies at the heart of services for children in public care. The key message of this paper is that a Munro approach can transform looked after childhoods. However, the current ‘child protection’ model of social work in England may prevent this shift in social work practice.  相似文献
