语言正在全球5个热点地区快速消亡

语言学家警告说,每两个星期就至少有一种语言从地球上消亡。语言消亡这种现象是语言自身进化中的一个阶段还是退化中的一个阶段?在一些语言消亡的同时,一些新的语言也在出现。我们要尽可能地挽救语言消亡给人类文化带来的损失,但就语言本身来说,我们也不需要过分恐慌……     

Behavioral Regulatory Problems Are Associated With a Lower Attentional Bias to Fearful Faces During Infancy

To investigate the role of early regulatory problems (RP), such as problems in feeding, sleeping, and calming down during later development, the association between parent-reported RP at 3 months (no-RP, n = 110; RP, n = 66) and attention to emotional faces at 8 months was studied. Eight-month-old infants had a strong tendency to look at faces and to specifically fearful faces, and the individual variance in this tendency was assessed with eye tracking using a face-distractor paradigm. The early RPs were related to a lower attention bias to fearful faces compared to happy and neutral faces after controlling for temperamental negative affectivity. This suggests that early RPs are related to the processing of emotional information later during infancy.     

Multimethod assessment of self-regulated learning in college students: different methods for different components?

Instructional Science - Although self-regulated learning (SRL) is seen as highly relevant for successful college learning, college students oftentimes show a lack in SRL abilities. Therefore, it...

NEGOTIATING POLITICIANS’ RESPONSIBILITIES IN NEWS INTERVIEWS

News interviews are contexts in which political responsibilities are articulated and negotiated. Although the accountability interview is recognized as a commonsense practice in journalism, and the research on political interviews is substantial, it partly remains to explore how responsibilities are negotiated in different forms of questioning in journalism. This study investigates three generic forms of questioning: accountability questioning, the clarifying of promises, and the principal assessments. Key features of the different forms are specified. The empirical study investigates how the questionings are performed in news on industrial crises in Sweden, in the different political regimes in the 1970s and the 2000s. The data consist of 27 news interviews with the formally responsible Ministers. The method is based on Conversation Analysis and includes detailed analyses of questions and answers. The study shows (1) how the forms of questioning differ when it comes to the action agenda and in how responsibilities are invoked and negotiated; (2) how the questionings tend to reproduce particular expectations of Governmental interventions; (3) how increased assertiveness and adversarialness in interviewing coincide with reduced expectations of political responsibilities.     

Exteroceptive cues in taste-aversion learning,no artifact: Reply to Holder

Holder (1988) has raised several objections to our work on the role of exteroceptive contextual stimuli in taste-aversion learning by rats. Our main conclusion from that work is that tongue-tactile stimuli from the drinking spout constitute the likely basis for findings of contextual bottle control over learned taste aversions. Holder suggests that our results are confounded by taste cues from the fluid containers. We refute this suggestion by presenting data from two experiments showing contextual bottle control, even though potential taste cues from the drinking bottles were eliminated. We also point to the fact that some of Holder’s criticisms are based on misreadings of our various reports.     

Adaptive progressive download based on the MPEG-4 file format

In this paper we describe how progressive download and adaptive streaming can be combined into a simple and efficient streaming framework. Based on the MPEG-4 file format (MP4) we use HTTP for transport and argue that these two components are sufficient for specifying an open streaming architecture. The client selects appropriate chunks from the MP4 file to be transferred based on (1) the header information (i.e. the “moov” box) in the first part of the file and (2) his observation of network throughput. The framework is completely client driven which allows for better server scalability and reduces signalling overhead. We discuss architecture and implementation issues such as complexity, interoperability and scalability and compare to 3GPP PSS Rel-6 adaptive streaming when appropriate. Measurements from a simple MP4/HTTP streaming client are presented showing that appropriate chunks are selected such that increased reliability is achieved.

The Relative Efficiency of Departments at a Turkish Engineering College: A Data Envelopment Analysis

In this study, Data Envelopment Analysis is used to measure relative efficiencies of academic departments of an engineering college. Input and output criteria are determined and measured utilizing the academic personnel performance measurement scheme of the College. New measures are developed to compare departments of different disciplines. The discriminating power of the measurement models is improved by restricting criteria weights directly and by using a multiple criteria decision making approach. Sensitivity of the results to exclusion of a criterion and changes in relative importance of the criteria is analyzed. Evaluation of the results jointly by the college administration and the departments is explained for a successful efficiency improvement mechanism.
