英语中名词性间接回指的认知语义解析

根据兰盖克的认知语法,英语中名词性间接回指的语义本质是基体—侧重有机结合体。名词性间接回指含有两个基本构成元素,即先行项和名词性回指项,但二者不共指。回指项的语义预设了先行项的意义,先行项的语义就成为名词性间接回指的基体。分析不同类型的名词性间接回指的语义特征,并指出名词性间接回指的语义是存在于认知主体大脑中的心理实体,它必然受到认知主体的认知域的限制,所以名词性间接回指的解读存在一定的个体差异性。     

Test for Trend With a Multinomial Outcome

ABSTRACT

There is no established procedure for testing for trend with nominal outcomes that would provide both a global hypothesis test and outcome-specific inference. We derive a simple formula for such a test using a weighted sum of Cochran–Armitage test statistics evaluating the trend in each outcome separately. The test is shown to be equivalent to the score test for multinomial logistic regression, however, the new formulation enables the derivation of a sample size formula and multiplicity-adjusted inference for individual outcomes. The proposed methods are implemented in the R package multiCA.     

非线性协整检验与“费雪效应”机制分析

本文分别在线性Engle-Granger协整模型和非线性指数平滑迁移自回归误差修正模型 (ESTAR-ECM) 的框架下,对我国名义利率与通货膨胀率序列进行了长期均衡关系的检验。发现线性协整模型不能捕捉到我国名义利率与通货膨胀率的长期均衡关系,而对于ESTAR-ECM模型,无论利用商业银行1年期贷款利率还是7天期银行间同业拆借利率作为名义利率的代理变量,均证实名义利率与通货膨胀率具有长期稳定的均衡关系,表明“费雪效应”在我国是成立的。但由于“费雪效应”系数小于1,表明名义利率与通货膨胀率之间仅存在弱的“费雪效应”。其意义在于,我国利率政策对稳定通胀预期、抑制通货膨胀具有一定的正面效应,但由于利率对通货膨胀反应不足,导致完全依靠利率政策控制目前较高的通货膨胀有一定的困难。     

The trinity of wage setting in EMU: A policy proposal

Diverging labor cost developments are often considered to be one of the most important factors that led to large current account imbalances in the euro area (EA) in the run-up to the global financial crisis. It has also been shown that wage growth differentials have significantly lowered the co-movement of EA countries’ business cycles – the most widely used meta-criterion for optimum currency areas. Against this background, this paper develops a wage-setting benchmark that aims to keep the economy in internal equilibrium and to maintain price stability, while it also exhibits the capacity to correct for external imbalances. The proposed wage benchmark is very simple and may serve as an anchor for the macroeconomic dialogue in Economic and Monetary Union. In order to demonstrate the potentially beneficial effects of such a wage benchmark we present some simulations showing how current account balances and labor costs would have developed across EA countries if the rule had served as a benchmark already in the run up to the crisis.

Experiences of Post‐Qualifying Study in Social Work

This article is based on a research project to explore the experiences of past and current candidates for post‐qualifying awards in social work in England. Also included in the study are the Leads of the post‐qualifying consortia in England. The study used questionnaire survey and nominal group techniques to gather data, which were coded and categorised into themes. The main findings relate to the perceived purposes of post‐qualifying study, motivations for undertaking post‐qualifying study, the factors that sustain and hinder study, the advice that those who have or who are experiencing post‐qualifying study would give to those about to start and future plans and hopes in this area.

Post‐qualifying study is generally valued, especially in relation to the opportunities it provides for professional development. The support of a mentor who has direct experience of the candidate's programme is highly prized, as are clear and consistent guidance from the programme and meaningful study time and workload relief from employers. There are also frustrations for some candidates who do not feel that their post‐qualifying study has stretched them beyond qualifying standards or who experience the teaching as divorced from the realities of daily practice. The appetite for a wider choice of post‐qualifying modules suggests that providers of post‐qualifying study will need to collaborate within and across regions in order to achieve a critical mass of candidates for more specialist or focused learning. The study suggests a need for further research to understand the impact of post‐qualifying study on candidates' social work practice.

The article concludes with two checklists of questions, one for individual candidates and another for agencies and programmes. These questions arise from the findings in the research.     

Building multivariable prognostic and diagnostic models: transformation of the predictors by using fractional polynomials

To be useful to clinicians, prognostic and diagnostic indices must be derived from accurate models developed by using appropriate data sets. We show that fractional polynomials, which extend ordinary polynomials by including non-positive and fractional powers, may be used as the basis of such models. We describe how to fit fractional polynomials in several continuous covariates simultaneously, and we propose ways of ensuring that the resulting models are parsimonious and consistent with basic medical knowledge. The methods are applied to two breast cancer data sets, one from a prognostic factors study in patients with positive lymph nodes and the other from a study to diagnose malignant or benign tumours by using colour Doppler blood flow mapping. We investigate the problems of biased parameter estimates in the final model and overfitting using cross-validation calibration to estimate shrinkage factors. We adopt bootstrap resampling to assess model stability. We compare our new approach with conventional modelling methods which apply stepwise variables selection to categorized covariates. We conclude that fractional polynomial methodology can be very successful in generating simple and appropriate models.     

Multi-group segregation for nominal and ordinal categorical data: An application to socio-religious groups in India

This study is an attempt to construct some summary measures of multi-group segregation for nominal and ordinal categorical data. These measures are developed by taking into account the association between identity groups and unordered or ordered categories of the well-being indicator and also the disproportionate representation of the populations of the identity groups across the unordered or ordered categories of the well-being indicator. The newly developed measures are characterized and applied to assess the disparities in education and occupational status among the socio-religious groups in India. Empirical findings reveal the existence of between-group inequality in education and occupation in India, and some relevant policies to reduce these inequalities are also suggested.     

发展中国家贸易自由化与汇率政策配合的理论和经验研究

发展中国家进行贸易自由化改革 ,根本目的是为了提高资源配置效率 ,促进本国经济的发展。从对发展中国家贸易自由化与汇率政策配合的理论和经验研究中可以看出 :运用灵活的汇率政策配合贸易自由化改革 ,有利于发展中国家在进行贸易自由化改革过程中减少经济的调整成本 ,确保贸易自由化改革的成功实现。中国加入世界贸易组织之后 ,仅仅依靠积极的财政、货币政策是不够的 ,应选择具有较大弹性的汇率制度 ,采取灵活的名义汇率贬值政策配合贸易自由化 ,从而实现内外均衡 ,以最低的代价成功地完成贸易自由化改革
