An asymptotic theory for semiparametric generalized least squares estimation in partially linear regression models

Consider a partially linear regression model with an unknown vector parameter β, an unknown functiong(·), and unknown heteroscedastic error variances. In this paper we develop an asymptotic semiparametric generalized least squares estimation theory under some weak moment conditions. These moment conditions are satisfied by many of the error distributions encountered in practice, and our theory does not require the number of replications to go to infinity.     

Room to move? Professional discretion at the frontline of welfare‐to‐work

Outcomes of social policies have always been mediated by the discretionary agency of front‐line staff, processes which nevertheless have received insufficient attention in policy evaluation and in the social policy literature more broadly. This article takes the case example of the policy reforms associated with the Australian government's welfare‐to‐work agenda. Drawing on two discreet research projects undertaken at different points in the policy trajectory, the practices of social workers in Centrelink – the Commonwealth government's primary service delivery agency involved in welfare‐to‐work – is examined. Centrelink social workers have been and remain one of the core groups of specialist staff since the Department's inception in the late 1940s, working to improve the well being of people in receipt of income security. Their experiences of the recent past and their expectations of the future of their professional practice as welfare reform becomes more entrenched are canvassed. In summary, the discretionary capacity of the Centrelink social workers to moderate or shape the impact of policy on income security recipients is steadily eroding as this group of professionals is increasingly captured by the emerging practices of workfare.     

Reconsidering public relations models

This essay examines some of the methodological and conceptual problems involved in measuring public relations models. The analysis suggests that there are several contradictions between the relationship management metaphor underlying this work and how public relations models are conceptualized and measured.Drawing on examples from the historical evolution of leadership studies, the authors argue that “public relations models” need to be measured at the relational level, rather than being aggregated across publics and relational stages. They also argue that an adequate normative theory of organizational practice will have a developmental component built into it.     

中西文化的不同特质

《恩底米安》与济慈诗歌的神话唯美主义

《恩底米安》体现了济慈诗歌的神话唯美主义倾向,显示出神话入诗的独特审美魅力,这一创作取向在西方浪漫派的诗歌中是最重要的精神特征。不过,《恩底米安》在艺术上过分追求诗境的梦幻效果,导致神话诗思的迟滞和感性想象过分主导了诗歌的情调,这是我们应该予以重视的。从《恩底米安》的分析中可见诗歌与神话的现代关联,显示了诗歌创作的多种思想与审美可能。     

建国初华东区保存富农政策执行情况解析

新中国成立初期,中共中央针对新区土地改革制定了保存富农经济的政策。在实际执行政策过程中,华东区根据地方调查情况,较好地执行了保存富农经济的政策。华东区之所以能较好的执行保存富农经济的政策,是与华东区农村调查的客观情况和地方领导人主观思想两个方面分不开的。这为建国初华东区经济的迅速恢复和发展创造了条件。
