Corporate statement serving as information subsidies in the product-harm crisis

This study explores the attributes of a crisis statement which influence its utility as an information subsidy in the process of product-harm crises in China. Through investigating and analyzing 92 statements released in times of product-harm crises, the results show that the form in which the statement is released, and the length of the statement have significant effects on whether the statement will be quoted fully or partially by the news media.     

Resource characteristics in social exchange networks: Implications for positional advantage

Despite the wide range of resources that traverse social networks, social exchange research has focused on only a narrow subset. Notably, prior social exchange research has not considered resources like information that have the capacity to diffuse through networks. The current study investigates how differences between the standard social exchange resource and an information-type resource affect the advantage provided by one's network position. Results of a laboratory experiment support predictions and offer two new insights to the foundations of positional advantage: (1) the location of advantageous positions in a network differs by resource characteristics, and (2) only in particular situations is a single position able to experience high levels of both power and exchange frequency.     

Information

Information technology is increasingly being used in the human services, but reports suggest that some professionals are resisting its introduction. Some accounts for this resistance emphasise the role of the technology's physical attributes. It may, however, be due more to mistaken assumptions by some professionals about the role of the technology in generating information in human service contexts. Information as a concept has different interpretations according to its usage. It is the author's contention that there has been a failure to differentiate between the use of the concept in different settings and this is a possible causal factor in producing resistance. This paper examines information as used in communication theory and the human services and emphasises the need for a thorough examination of the role of information in professional social work education and practice.     

Schur optimality of one-way designs

In comparison of treatments using homogeneous experimental units, it is shown that a design is Schur optimal when treatment replications are as equal as possible.     

Generalized Weibull Linear Models

For the first time, a new class of generalized Weibull linear models is introduced to be competitive to the well-known generalized (gamma and inverse Gaussian) linear models which are adequate for the analysis of positive continuous data. The proposed models have a constant coefficient of variation for all observations similar to the gamma models and may be suitable for a wide range of practical applications in various fields such as biology, medicine, engineering, and economics, among others. We derive a joint iterative algorithm for estimating the mean and dispersion parameters. We obtain closed form expressions in matrix notation for the second-order biases of the maximum likelihood estimates of the model parameters and define bias corrected estimates. The corrected estimates are easily obtained as vectors of regression coefficients in suitable weighted linear regressions. The practical use of the new class of models is illustrated in one application to a lung cancer data set.     

分科型艺术课程的教育价值探讨

当前中小学艺术教育实行的是一种单一的、刻板的、功利的传统分科型艺术课程,其最大的弊端是使艺术教育中的情感和技艺、人文素养和艺术知识的分离,单纯追求某一艺术学科的知识和技艺。分科型艺术课程已不适应当前艺术教育的发展,必须对其进行扬弃与改革。     

Simulated Distribution of the Kullback-Leibler Information Measure

This paper provides the percentiles obtained by simulation of an informational test statistic. It gives evidence that the widely used chi-square approximation to this test statistic is not suitable.     

场域转换与文化反哺:青年群体与变迁社会的信息互动

以布迪厄场域理论来考察不同社会形态下青年与社会的信息互动实践,发现青年与社会的信息互动在具有“位置-权力”关系的场域中展开,“位置-权力”关系通过信息资本的占有而建构。社会形态随技术变革更迭,青年与社会信息互动的场域逻辑与运行机制发生相应转变。从农耕社会到工业社会再到信息社会,青年与社会的互动场域变得多样,并且发生着从家庭向学校再向网络空间的偏向性转换,场域运行的推动力量也从时间权威向结构权威再向认同权威转换。可以说,青年与社会信息互动场域的转换,正是人类在不同社会形态下对“用时间消灭空间”的信息传播时空观的生产实践与社会表征。     

Computer Diffusion and Worker Empowerment

Abstract

Much anecdotal material describes various human impacts of computer adoption within the social work profession, however, there is scant research which confirms or challenges these assumptions. This article describes a study which investigates the diffusion of computers into the social work profession in terms of empowerment as an individual outcome for workers. A questionnaire returned by 520 social workers provided data on organizational computer diffusion, organizational centralization, and the Social Worker Empowerment Scale. Workers in organizations where computer diffusion was more advanced, and those in more decentralized decisionmaking environments were found to be more empowered.
