政府话语权：流失、分散与重构——基于微博的考察

随着网络技术的发展,以微博为代表的新媒体时代已经来临,成为影响政府话语权的重要因素。政府掌握着网络话语权的主导权,但由于民众权利意识觉醒、政府信息公开程度较低、政府难以及时回应、政府信息的发布“不接地气”等使得政府与民众的互动不足,网络话语平权使得政府话语权被分散、流失。政府在网络话语权的争夺中要加大信息公开的力度,正确对待网络言论,打击与疏导并重,建立政务微博运营团队,转变对话方式,将单向传递改为多向互动。     

国有企业改制中国有资产流失的原因分析及法律对策

国企改制中的国有资产流失可分为两个阶段 ,一是在改制过程中由于低估、折股造成的损失 ,二是在改制后国有股运营中造成的利益损失。流失的主要原因是没有健全国有资产监管体制 ,资产评估不依法规范进行以及国有股不能上市流通。遏制国有资产流失主要在于尽快完善国有资产运管体制 ,严格规范资产评估行为 ,尽快实现国有股上市流通     

多路径效应下的远距支援干扰压制区

在不同反射系数不同雷达载频下,利用方向图传播因子计算了远距离支援干扰压制区。借助雷达与目标之间以及雷达与干扰机之间的传播链路上的方向图传播因子,推导出信号干扰噪声比;利用渐削矩形口径,采取台阶余弦平方加权因式抑制背瓣的方法建立了天线模型;根据反射系数定义以及直射线和反射线的波程差得到了方向图传播因子的计算模型。仿真结果表明,多路径效应使得干扰压制区范围扩大,区域出现分裂现象;反射系数减小,暴露区域相应地缩减,但是暴露区的外形没有改变;雷达载频越高,方向图因子起伏越大,可借助宽带雷达载频的多样性来减轻或尽可能地利用多路径效应。     

Estimating the exponential reliability function for a system in series with type II censored data

The problem of estimating the one parameter exponential reliability function for a system composed of l componentes in series is considered. Under the type II censoring scheme, the Bayes nature of the minimum variance unbiased estimator is demonstrated and the admissibility of related generalized Bayes estimators is established. For the one component case, the best unbiased estimator is admissible.     

Health Technology Literacy: A Transdisciplinary Framework for Consumer-Oriented Practice

Abstract

The present study developed a typology of self-reported coping strategies used by older adults in adapting to vision impairment using qualitative analyses. Narrative data were examined from three previous quantitative studies of adaptation to vision loss. Major themes in coping with vision loss included difficulty in balancing norms of independence with the functional losses resulting from eye disease, and the importance of the informal social network. Importantly, a number of coping mechanisms that have not been examined in prior quantitative work were identified through the present qualitative analyses. Implications of this typology of self-reported coping with age-related vision loss for research and practice are discussed.     

Ridge regression estimators in the linear regression models with non-spherical errors

The present paper considers a family of ordinary ridge regression estimators in the linear regression model when the disturbances covariance matrix depends upon a few unknown parameters. An asymptotic expansion for the distribution of the ridge regression estimator is developed and under the quadratic loss function its asymptotic risk is compared with that of the feasible GLS estimator.     

Estimation of signal to noise ratio using mahalanobis distance

In this paper, we propose some alternative estimatiors to that given by C. G. Khatri and C. R. Rao (1985), for estimating Signal to Noise ratio. Using Pitman Nearness, Condition for prefering one estimator over the other is estabilished. It is shown numerically that estimators corresponding to Entropy loss function are better more oftern than those corresponding to Squared Error loss.     

Understanding Ambiguous Loss in the Context of Dementia Care

Abstract

This study examined the experience of ambiguous loss for family members caring for a person with dementia living in a long-term care facility. Data for this study came from in-depth, active interviews conducted with 38 adult daughters and 23 adult sons caring for a parent with dementia living in a long-term care facility. The stories shared by the adult children revealed that ambiguous loss in the dementia context involves a long, on-going process of several phases including anticipatory loss, progressive loss and acknowledged loss. The nature of the ambiguity shifts and the experience changes for families as they journey through the ambiguous loss process. Acceptance and avoidance were the two most common coping strategies used in dealing with acknowledged loss.     

Missing siblings: seeking more adequate social responses

Little is known about the experience of family and friends when a young adult goes missing, less is known about how siblings make sense of the experience. Police assistance to locate the missing person may be sought but there is little recognition of going missing or missingness as a social issue, and there is little or no adequate social response to the needs of those left behind. This paper links knowledge of siblings, loss and grief to an understanding of this phenomenon. It presents the methodology and findings of an exploratory, qualitative study into the experiences of nine adult siblings of long-term missing people in Australia and presents the themes drawn from their accounts. The themes are briefly elaborated using direct quotations from participants in the study and represented in a diagram. The paper seeks to develop greater understanding of the inter-relationship between missingness and other social issues, to give voice to the views of participants and to encourage practitioners to engage more purposefully in work with family and friends affected by this issue. Some implications for social work practice are presented.     

ESTIMATION OF THE PARAMETER OF A POISSON DISTRIBUTION USING A LINEX LOSS FUNCTION

This paper considers estimation of the parameter of a Poisson distribution using Varian's (1975) asymmetric LINEX loss function L (δ) = b{exp(aδ) - aδ - 1}, where δ is the estimation error and b > 0, a 0. It is shown that for a < 0, the sample mean X¯ is admissible whereas for a > 0, X¯ is dominated by c*X¯, where c*= (n/a)log(1+a/n). Practical implications of this result are indicated. More general results, concerning the admissibility of estimators of the form cX¯+ d are also presented.
