An Approach to Event-Driven Software Testing

In this paper, the testing technology of event-driven software is focused. It is first analyzed the difference between event-driven software and the traditional procedure-oriented software, and based on the above analysis, the mechanism of event-driven and the effect of introduction of event-driven mechanism on software testing are unveiled. Then based on the characteristic of the event-driven software, the traditional software testing method is improved, and testing policy of event based test is presented in this paper.Moreover the event coverage criteria are defined and given here. At the same time the event executing rule are further uncovered, such as ordinal event, non-ordinal event, predecessor event and concurrent event etc., and also the methods of testing according to event executing rule are studied.

Communicating Agencies＇ Humanitarianism in Natural Disaster and Armed Conflicts＂ Differences, Challenges, and Dilemmas

The literature on disasters mainly focuses on natural disasters and looks at their coverage by the media. The paper argues that armed conflicts are also disasters and that Western relief agencies intervening in natural disasters and conflict are also proactive communicators. Taking a different approach from much of the available research, it explores agencies＇ communication work in these two types of crises and analyses the differences, challenges and dilemmas that they face in communicating their humanitarianism. It outlines the distinguished inherent characteristics of natural disasters and conflicts, and examines their impact on the understanding of the crises, the perception of affected populations, and the implementation of agencies＇ actions. It also investigates how, in turn, all these features influence agencies＇ communication practices that in natural disasters emergencies and conflict-related crises perform a different role and show different parameters. In this sense, the paper distinguishes between ＂humanitarian communication＂ to refer to the former, and ＂humanitarian advocacy＂ to refer to the latter. The paper briefly explores the operational challenges engendered by the contested interpretations of humanitarian advocacy, shows that the use of the parameters of humanitarian communication in conflict-related crises to overcome these problems caused additional concern, and presents two forms of humanitarian advocacy engendering less challenges and dilemmas.

Surface Soil Properties Influence Carbon Oxide Pulses After Precipitation Events in a Semiarid Vineyard Under Conventional Tillage and Cover Crops

In semiarid regions of the Mediterranean basin, a rainfall event can induce a respiratory pulse that releases a large amount of soil carbon dioxide （CO2） into the atmosphere; this pulse can significantly contribute to the annual ecosystem carbon （C） balance. The impacts of conventional tillage and two different cover crops, resident vegetation and Bromus catharticus L., on soil CO2 effiux were evaluated in a Vitis vinifera L. vineyard in La Rioja, Spain. Soil CO2 efflux, gravimetric water content, and temperature were monitored at a depth of 0-5 cm after rainfall precipitation events approximately every 10 d in the period from May 17 to July 27, 2012, during which the cover crops had withered. Additionally, on June 10, 2012, soil organic C, microbial biomass C, and I^-glucosidase activity were determined at soil depths of 0-2.5, 2.5-5, 5-15, and 15-25 cm. The results show that pulses of soil CO2 were related to the increase in soil water content following precipitation events. Compared to the conventional tillage treatment, both cover crop treatments had higher soil CO2 efflux after precipitation events. Both cover crop treatments had higher soil organic C, microbial biomass C, and β-glucosidase activity at the soil surface （0-2.5 cm） than the conventional tillage treatment. Each pulse of CO2 was related to the surface soil properties. Thus, this study suggests that the enhancement of soil organic C and microbiological properties at the soil surface under cover crops may increase soil CO2 efflux relative to conventional tillage immediately after precipitation events during the dry season.

Holocene vegetation change in relation to fire and volcanic events in Jilin, Northeastern China

Volatiles erupted from large-scale explosive volcanic activities have a significant impact on climate and environmental changes.As an important ecological factor,the occurrence of fire is affected by vegetation cover,and fire can feed back into both vegetation and climatic change.The causes of fire events are diverse;and can include volcanic eruptions.The amount of charcoal in sediment sequences is related to the frequency and intensity of fire,and hence under good preservation conditions fire history can be reconstructed from fossil charcoal abundance.Until now,little research on the role of fire has been carried out in northeastern China.In this study,through research on charcoal and tephra shards from Gushantun and Hanlongwan,Holocene vegetation change in relation to fire and volcanic events in Jilin,Northeastern China,was investigated.Where tephra shards are present in Gushantun it is associated with low level of both conifers and broadleaved trees,and is also associated with a pronounced charcoal peak.This suggests forest cover was greatly reduced from a fire caused by an eruption of the Tianchi volcano.We also detected one tephra layer in Hanlongwan,which also has the almost same depth with low level forest pollen values and one charcoal peak.This was caused probably by an eruption of the Jinlongdingzi volcano.
