Similar coefficient for cluster of probability density functions

In this article, we propose a new criterion to evaluate the similarity of probability density functions (pdfs). We call this the criterion on similar coefficient of cluster (SCC) and use it as a tool to deal with overlap coefficients of pdfs in normal standard on [0;1]. With the support of the self-update algorithm for determining the suitable number of clusters, SCC then becomes a criterion to establish the corresponding cluster for pdfs. Moreover, some results on determination of SCC in case of two and more than two pdfs as well as relations of different SCCs and other measures are presented. The numerical examples in both synthetic data and real data are given not only to illustrate the suitability of proposed theories and algorithms but also to demonstrate the applicability and innovation of the proposed algorithm.     

The dual-continuum approach: An extension of the contingency theory of strategic conflict management

This article examines the limitations of using a single advocacy-accommodation continuum when depicting organizational stance and movement in conflict situations (Cancel et al., 1997). The authors argue that advocacy and accommodation can vary independently in response to a variety of contingent factors. To comprehensively capture the locations and motions that are possible in organization-public conflicts, a two-continuum approach is proposed. Separate assessment of the effects of contingency variables on advocacy and accommodation can be used to accurately locate organizational stance along advocacy and accommodation continua. Strategic alternatives that cannot be depicted using a single continuum (such as favorable alignment of organization advocacy/public accommodation or unilateral change on the part of one party) can be captured if separate continua are employed. By depicting initial stances and desired directions of movement for both the organization and public, the dual-continuum approach can also provide practical guidance to public relations professionals in selecting strategies for achieving preferred outcomes and evaluating their effectiveness.     

Open Data on a Closed Shop? Assessing the potential of transparency initiatives with a focus on efforts to strengthen capacity development support

Despite strong political commitment, actual gains in improving accountability in development co‐operation have been limited. Main reasons for this include the low level of transparency and high number of actors, as well as the limitations of the self‐reported and input‐oriented OECD reporting system. Efforts through the International Aid Transparency Initiative (IATI) and related transparency initiatives are ill‐equipped to change this given their decision to adhere to the same system. This article uses the specific area of support to capacity development to illustrate this. While further disaggregation of reporting on technical co‐operation could respond to a transparency gap, overcoming the accountability gap requires moving beyond promoting ‘supply‐side’ reform and re‐engaging in efforts to promote collective action.     

Editorial

Undergoing a traumatic experience can be a life-changing event, having a significant impact on individuals, families, communities, workplaces and societies. Traumatology is therefore a complex field of study demanding a sophisticated level of understanding to serve as a theory base. This article explores the potential for existentialist philosophy to make an important contribution to our understanding of trauma and its effects. It presents trauma as an existential injury and explores the psychosocial basis of traumatic experience — that is, conceptualising trauma as having both psychological and sociological dimensions, the combination of which has profound existential resonances. While the theoretical ideas discussed can be applied to trauma at any stage in the life course, this paper focuses in particular on childhood trauma. Consequently, child abuse is used as an example of how trauma can have a significant (and detrimental) effect on identity development, invoking a need for a commitment to trauma recovery.

词块与语言教学

不少语言学家在语言研究过程中对词汇和句法之间存在的同时兼有词汇和句法特征的板块结构给予了关注，并由此提出了词汇法教学。词块自身的特点和优势决定了加强词块教学可以提高学习者语言产出的能力，即英语口语能力及写作能力。     

What is a person‐centred approach? Familiarity and understanding of individualised funding amongst carers in New South Wales

Person‐centred approaches place individuals with a disability at the centre of decision making, with their carers and family invited to be partners in the process. Rather than being required to fit within existing service programs, person‐centred approaches enable individuals to choose the support options that best meet their needs. In order to facilitate this, person‐centred approaches will be accompanied by the introduction of individualised funding. This means the individual will be provided with funding to purchase services of their choosing. Given these significant changes occurring in the disability sector, Carers NSW surveyed informal carers of people with a disability to identify what they knew about person‐centred approaches and how they felt about their introduction. Survey results indicate that there is a need to increase the capacity and willingness of carers significantly in order to engage with person‐centred approaches and individualised funding. Carers require targeted and comprehensive information about these concepts in order to understand fully the changes occurring within the disability sector. These findings also indicate specific areas that need to be addressed in order to increase carers' awareness of these concepts and also to address existing negativity and confusion.     

“90后”大学生综合英语课堂教学反思

综合英语是英语专业基础阶段的一门主要课程,目的在于培养学生的听、说、读、写的综合能力。面对时尚新潮的＂90后＂,教师发现综合英语课上效果不理想。这种不良学习状态是由多方面原因造成的。由于在学校范围内,本文只对教与学两方面原因进行分析。教师完全摒弃传统的教学法,注重交际方法教学反而与普通学习者的实际脱节,近几年来学生的学习状态一直下滑,为了提高学生的学习效果,综合英语的教学方法还有待于反思,＂以学生为中心＂的教学理念也因此受到质疑。     

Bayesian adaptive dose‐escalation designs for simultaneously estimating the optimal and maximum safe dose based on safety and efficacy

The main purpose of dose‐escalation trials is to identify the dose(s) that is/are safe and efficacious for further investigations in later studies. In this paper, we introduce dose‐escalation designs that incorporate both the dose‐limiting events and dose‐limiting toxicities (DLTs) and indicative responses of efficacy into the procedure. A flexible nonparametric model is used for modelling the continuous efficacy responses while a logistic model is used for the binary DLTs. Escalation decisions are based on the combination of the probabilities of DLTs and expected efficacy through a gain function. On the basis of this setup, we then introduce 2 types of Bayesian adaptive dose‐escalation strategies. The first type of procedures, called “single objective,” aims to identify and recommend a single dose, either the maximum tolerated dose, the highest dose that is considered as safe, or the optimal dose, a safe dose that gives optimum benefit risk. The second type, called “dual objective,” aims to jointly estimate both the maximum tolerated dose and the optimal dose accurately. The recommended doses obtained under these dose‐escalation procedures provide information about the safety and efficacy profile of the novel drug to facilitate later studies. We evaluate different strategies via simulations based on an example constructed from a real trial on patients with type 2 diabetes, and the use of stopping rules is assessed. We find that the nonparametric model estimates the efficacy responses well for different underlying true shapes. The dual‐objective designs give better results in terms of identifying the 2 real target doses compared to the single‐objective designs.     

转变发展方式必须率先转变调整结构的方式

面对新的发展形势和经济任务，应该明确提出产业结构调整的新思路，即政府创造条件，靠市场来调结构。“十二五”期间，最优先考虑的问题应该是如何改革、如何转变结构调整的方式。倘若“调结构”的方式、特别是实体经济中制造业“调结构”的方式不能率先改革，转变发展方式的诸多目标就有可能落空。“十二五”期间的政策落脚点在于继续加快培育“统一开放、竞争有序”的现代市场体系的进程，切实贯彻中央一再强调的“资源配置要建立在市场调节的基础上”的施政原则，把产业结构的市场化调节落到实处。对于以制造业为基础的结构存量调整的方式，要基本实现从行政化到市场化的转变，强化金融、商贸等服务业的疏导、中介功能，创建有利于推进服务业深度参与存量结构调整和产业升级的体制政策环境。
