Operational oceanography in Indonesia

In 2005 Indonesian and European institutes joined to start the first step for the implementation of an Ocean Operational System in the Indonesian archipelago. The system will support the decision making process for the sustainable use of marine resources, providing useful information and added value products as well as a service for an improved management of the sea with high business impact to targeted groups as public authorities and commercial operators (coastal managers, fishermen, shipping companies). In this paper the System is shortly described with its potential benefits and economic and social impacts.

A Systematic Approach to Evaluating the Effects of Collaborative Negotiation Training on Individuals and Groups

Negotiation training evaluation tends to be short-term, aspectual and piecemeal; evaluations often focus on only one or two salient outcomes of training. This essay presents a model for negotiation training evaluation research that offers a broad conceptualization of the hypothesized individual and group-level effects of training in collaborative negotiation. The model assesses change at the individual level in conflict-related cognitions, attitudes, affect and behaviors; and at the group level in conflict outcomes and work climate. The Negotiation Evaluation Survey (NES), a time-delayed, multi-source feedback approach to assessment and development, is presented as a means of addressing some of the conceptual and methodological problems inherent in more common methods of training evaluation. An illustrative assessment of one model of collaborative negotiation training for adults, the Coleman/Raider Model, is presented. The results, implications, and future research challenges are discussed.     

利用aroA基因建立鸡传染性鼻炎PCR诊断方法

利用aroA基因设计了1对引物,分别对10株标准副鸡嗜血杆菌(HPG)菌株、14株分离的HPG菌株进行PCR扩增,结果均得到了与预期大小一致的片段,而对10株非HPG菌株和3株病毒进行扩增则无相应片段产生;该PCR能检测出10个菌细胞.与常规PCR方法相比,aroA-PCR的敏感性更高.     

Firearm examination: Examiner judgments and computer‐based comparisons

Forensic firearm examination provides the court of law with information about the source of fired cartridge cases. We assessed the validity of source decisions of a computer‐based method and of 73 firearm examiners who compared breechface and firing pin impressions of 48 comparison sets. We also compared the computer‐based method's comparison scores with the examiners' degree‐of‐support judgments and assessed the validity of the latter. The true‐positive rate (sensitivity) and true‐negative rate (specificity) of the computer‐based method (for the comparison of both the breechface and firing pin impressions) were 94.4% and at least 91.7%, respectively. For the examiners, the true‐positive rate was at least 95.3% and the true‐negative rate was at least 86.2%. The validity of the source decisions improved when the evaluations of breechface and firing pin impressions were combined and for the examiners also when the perceived difficulty of the comparison decreased. The examiners were reluctant to provide source decisions for "difficult" comparisons even though their source decisions were mostly correct. The correlation between the computer‐based method's comparison scores and the examiners' degree‐of‐support judgments was low for the same‐source comparisons to negligible for the different‐source comparisons. Combining the outcomes of computer‐based methods with the judgments of examiners could increase the validity of firearm examinations. The examiners' numerical degree‐of‐support judgments for their source decisions were not well‐calibrated and showed clear signs of overconfidence. We suggest studying the merits of performance feedback to calibrate these judgments.
