Using information-systems constructs to study online- and telephone-banking technologies

The research literature has seen a number of studies aimed at understanding customer attitudes towards banking technologies, and thereby providing implications for developmental planning and marketing. However, even though banking technologies have a significant amount of information systems (IS) component to them, there is a paucity of research that considers them from the IS perspective. In this paper, we fill this gap by considering three constructs, namely usefulness, ease of use and usage, that are all rooted in the IS literature. We study user’s perceptions of these constructs, as well as the relationships among them, for both online and telephone banking.     

Possibilities and problems with the use of models as a communication tool in water resource management

Politicians and policy-makers, as well as modellers, often nurses an expectation that model derived results is an objective source of information that can be used to support decisions. However, several prerequisites have to be dealt with in order to ensure that models can be used as legitimate and efficient tools in water resource management. Based on empirical material from recent studies on the use of models in stakeholder dialogues, mainly focusing on catchment nutrient transport, two central problems are identified: (a) Models are laden with choices and thus depend on assumptions and priorities of modellers. (b) There are several factors that influence ability and willingness of stakeholders (as information recovers) to criticize or accept results of the modelling exercise. Recognized factors likely to influence stakeholders' acceptance of model derived results include issues at stake, stakeholders' ability to criticize model derived information, and their trust in the institutions that have developed or applied the used models. Identified prerequisites for successful use of models in integrated water resource management include: consideration of user relevance, awareness of and preparedness to handle constraints linked to communication of model-based results, transparency of used models and data and of involved uncertainties, mutual respect between experts and stakeholders and between involved stakeholder groups, a robust institutional network, and sufficient time for dialogues. Development and use of strategies for participatory modelling, based on a continuous dialogue between experts and stakeholders is recommended as a way to facilitate that the prerequisites for a successful use of models in water resource management are fulfilled.

Using linear models in optimizing parameters of time-triggered protocols

A mechanism of synchronization of components of distributed systems in which communications are based on a common time schedule for all system components is illustrated by examples of simple Time-Triggered Protocols. For parametric linear models of synchronization, the optimization problem is considered for a parameter that should exclude the overlapping of messages in communication channels. The results of using numeric methods for estimation of the optimal value of this parameter are described. __________ Translated from Kibernetika i Sistemnyi Analiz, No. 3, pp. 24–32, May–June 2006.     

辽东含硼岩系条痕状角闪混合岩特征及其找矿意义

痕状角闪混合岩与其围岩变（浅）粒岩为渐变过渡关系.并呈现一些特殊的结构构造.其岩石化学成份变化波动性较大,说明岩石化学成分不稳定,与矿化含量的不稳定性一致.其特殊的岩石化学组成显示为混合岩特征.条痕状角闪混合岩石稀土总量ΣREE的平均值为207.18 ppm;（Ce/ΣY平均值为3.25;La/Yb为平均值为 6.48,δEu平均为 0.48,Eu/Sm平均值为0.16.这些特点与里尔峪组的各种变（浅）粒岩相似,是层状混合花岗岩.     

柴达木盆地北缘侏罗系沉积环境演变及其石油地质意义

柴达木盆地北缘(柴北缘)东段大煤沟剖面侏罗系沉积层序发育完整。下侏罗统岩性以细砾岩、细—粉砂岩与炭质泥岩和页岩的不等厚互层为特征,其中大煤沟组一、二段与辫状河三角洲平原相关的湖沼相炭质泥页岩较发育,多含叶肢介、双壳类和植物等静水环境生物化石,沉积环境为辫状河三角洲—滨浅湖体系;由3个中期基准面升降旋回构成1个长期旋回。中侏罗统厚层河流—冲积相砂砾岩较发育,化石面貌以介形虫和植物为主,沉积环境为扇三角洲—滨浅湖体系,中上部发育较深湖相沉积;由9个中期基准面升降旋回构成1个长期旋回。不同时期和地区的化石与岩相分布特征反映侏罗纪沉积中心由西向东迁移。构造活动和气候是沉积环境的主要影响因素,但前者起重要的控制作用。早侏罗世潮湿气候下的辫状河三角洲平原为柴北缘提供了重要的生烃母质,但中侏罗世中晚期半干旱气候更有利于形成高品质的烃源岩。图5表1参18

Contextual cues aid recovery from interruption: The role of associative activation.

A series of experiments introduced interruptions to the execution phase of simple Tower of London problems and found that the opportunity for preparation before the break in task reduced the time cost at resumption. Retrieval of the suspended goal was facilitated when participants were given the opportunity to encode retrieval cues during an "interruption lag" (the brief time before engaging in the interrupting task) but was impeded when these visual cues were subsequently altered following interruption. The results provide useful support for the goal-activation model (E. M. Altmann & G. J. Trafton, 2002), which assumes that context--at the points of both goal suspension and goal retrieval--is critical to efficient interruption recovery.

农村饮水工程适宜水质净化技术

农村饮水工程根据不同的原水水质条件，宜采用不同的水质净化技术。对地表水浑浊度长年低于20NTU、瞬间不超过60NTU原水，可采用微絮凝直接过滤加消毒或慢滤加消毒净化工艺；浑浊度长年低于500NTU、瞬间不超过1000NTU的原水，采用混凝沉淀（澄清）过滤、消毒的常规净水工艺。对于特殊水质如氟超标的地下水、砷超标的地下水、苦咸水及其他污染水，根据不同情况，可分别采用活性氧化铝吸附法、混凝沉淀法、多介质过滤法、铁盐混凝沉淀法、电渗析法、反渗透法等不同方式予以处理。
