Networking services may be broken down in a disaster situation while people in the disaster area(s) strongly demand networking services for both communication and information sharing among users. This requires the fast restoration of networking services to fulfil the demand–supply gap. Although there are a number of studies on restoring communication and networking in disasters, few studies have explicitly examined the service availability during the temporary and partial recovery process of network restoration. From the perspective of users in the disaster area, it is important to be able to communicate or share information with people whenever they want/need to do so. Therefore, partial and local recovery of the networking services also plays an important role for improving service availability in the disaster situations. To assess the restoration effectiveness of networking services with a measure of user satisfaction level, we propose to use instant networking service availability (I-NSA), a novel metric, and we examine the effectiveness of networking service restoration solutions using the metric. I-NSA allows us to clearly express the instant availability of networking services that drastically changes with the elapsed time from the disaster occurrence in disaster areas. This paper examines the effective improvement of I-NSA when Local-and-Instant Clouds (LI-Clouds) are applied to the disaster situation. LI-Cloud has been designed and practically developed to provide deployable networking services to users. We verify that LI-Cloud enables significant improvement on the I-NSA performance in the fast restoration of networking services.

An organizing framework of the long-term recovery process was developed, after studying first hand how 14 U.S. communities recovered from a major disaster. The framework depicts the dynamic processes that contribute to an efficient local recovery, including the three key elements identified and the inter-relationships among them. The three key elements are personal leadership, ability to act, and knowledge of what to do. Although only one of the disaster events investigated during the four-year study period was a major damaging earthquake, the framework developed appears to be useful for understanding the aftermath of many types of natural disasters. Information about an effective recovery process should be factored into earthquake hazard mitigation and preparedness efforts because sooner or later, whether we are ready or not, we will be recovering from a major earthquake.

To study the application effect of rapid rehabilitation nursing intervention in thoracic surgery nursing, this paper researches controlled trials. First, this paper sets up a control group and a test group. The control group uses traditional nursing methods for thoracic surgical nursing intervention, and the test group adds rapid rehabilitation nursing intervention based on traditional nursing intervention. In addition, the operation and rehabilitation conditions of the control group and the test group are the same. Moreover, this paper records rehabilitation information in real time, performs data processing through statistical methods, and conducts follow-up surveys on the rehabilitation process of patients. In addition, this paper compares nursing effects through data comparison and histogram comparison. From the research results, various parameters of the patient’s recovery process and the user satisfaction of the rapid rehabilitation can be seen. Furthermore, nursing is higher than those of the control group, which shows that the rapid rehabilitation nursing method can positively affect the nursing of thoracic surgery.

1. Two experiments are described investigating the effects of level of metabolism on (a) resistance to, and (b) recovery from, Notoedric scabies of rats. The progress and severity of the disease was measured by weekly counts of the number of lesions; the metabolic rate in some rats was raised by administration of iodinated casein and in others was depressed by methyl thiouracil.2. In normal rats, the initial severe phase of the disease was followed by a partial recovery with survival of a smaller population of parasites.3. This recovery process in established infestations was hastened by elevation and retarded by depression of the metabolic rate.4. Resistance to the development of severe disease was enhanced by elevation and reduced by depression of the basal metabolic rate.5. The level of the residual infestation, after the severe phase of the disease had passed, was also affected by the treatment, being decreased by the higher but increased by the lower metabolic rate.

<span>Service availability is one of the major requirements for user satisfaction. Several researches were conducted in recent years to find suitable infrastructure to enhance the availability. Even though both hardware and software are to be in good condition, in recent years, software faults are the major concern for service availability. Software aging is a type of software fault. Software aging occurs as a result of errors accumulation in the internal environment of the system leading to performance degradation. To manage software aging, technique used is software rejuvenation. There exist two kinds of approaches for studying software aging and deriving optimal software rejuvenation schedules. The two approaches are measurement based and model based. In model based approach, analytic models are built for capturing system degradation and rejuvenation process. In measurement based approach, attributes are periodically monitored and that may indicate signs of software aging. In this work, a prototype of measurement based model has been developed. The model captures the aging indicator metrics from cloud environment and rejuvenates once the system reaches aged status. The proposed model uses platform independent, non-intrusive technique for capturing metrics. The rejuvenation carried out after analysing the captured metrics, increases the availability of the service.</span>

More than a decade has passed since the launch of the first e-Government one-stop web portals, which concern central points for digital access by citizens, enterprises and government. Due to the broad audience that these portals serve, various analyses have been performed concerning their effectiveness with regard to service delivery; trustworthiness with regard to service availability; usability; accessibility; and user satisfaction etc. The results from these analyses have extreme interest for governments, since they reflect government strategic planning, internal efficiency and effectiveness, while they have been utilized for their upgrades. E-Government portal upgrade appears to be something usual and various updates have been observed in most portals during this timeframe. This paper addresses and important issue: “do e-Government portal updates enhance user satisfaction?” To this end, a comparative qualitative evaluation of some major e-Government portals is performed, with the use of the American Customer Satisfaction Index (ACSI) during 2009 and 2012.

Previous investigations have shown that the lipid composition of cerebral membranes and dopaminergic neurotransmission are changed under chronic α-linolenic acid diet deficiency in the rat. This study investigated whether these changes could be reversed and if the stage of brain maturation might play a role in the recovery process. The effects of reversion on the fatty acid (FA) composition and dopaminergic neurotransmission were studied in brain regions known to be affected by such deficiency (i.e., the prefrontal cortex and nucleus accumbens) in 2-month-old animals. Dopamine release under pharmacological stimulation was studied using a dual-probe microdialysis method. Vesicular monoamine transporters were studied using quantitative autoradiography. The reversal diet, with adequate levels of n-6 and n-3 polyunsaturated fatty acids (PUFAs), was given to deficient rats at different stages of development (0, 7, 14, or 21 days of age). The results showed that when given during the lactating period, this diet was able to restore both the FA composition of brain membranes and the parameters of dopaminergic neurotransmission studied. However, when given from weaning, it allowed partial recovery of biochemical parameters but no recovery of neurochemical factors.The occurrence of profound n-3 PUFA deficiency during the lactating period could therefore be an environmental insult leading to irreversible damage to specific brain functions.

Background. Disasters are increasingly more frequent events on our planet. During disaster the role of the occupational therapist will require a more specific operative framework within nongovernmental organizations and community health services. Design. Systematic review. Objective. The aim of this study is to evaluate the evidence that highlight occupational therapist’s role in disaster area through a systematic review. Materials and Methods. Research on MEDLINE was performed. All articles from 2005 to 2015 concerning rehabilitation and occupational therapy in disaster areas were included. Results. Ten studies were selected to be included in this review. Four interesting points emerged: the importance of having rehabilitation intervention in postdisaster situations, the necessity to include a rehabilitation team in the early phase of disaster response, the need to provide a method to address the difficult evacuation, and finding the safest method of transport of people with preexisting disabilities and new injuries. Conclusions. The amount of evidence with respect to specific intervention of the occupational therapist’s role in a disaster situation is limited. However some evidence suggests that it could be a good means for reducing the number of medical complications and deaths of persons with preexisting disabilities. The evidences found highlight the necessity to create a multidisciplinary team addressing needs in disasters situation, in which the occupational therapist could certainly contribute.

The Impact

Abstract We measure the longer-term effect of a major earthquake on the local economy, using night-time light intensity, and focus on the role of insurance payments for damaged residential property in the recovery process. The destructive Canterbury Earthquake Sequence (2010–2011) in New Zealand is our case study. Uniquely, for this event, &gt;95% of residential housing units were covered by insurance and almost all incurred some damage. However, insurance payments were staggered over 5 years, enabling us to identify their local impact on recovery. We find that night-time luminosity can capture the process of recovery; and that insurance payments contributed significantly to the process of local economic recovery after the earthquake. Cash settlement of claims was no more effective than insurance-managed repairs in generating local recovery. Notably, delayed payments were less affective in assisting recovery; this suggests an important role for the regulator in making sure insurance payments are made promptly after disaster events.

In June, 2008, the People’s Bank of China (PBC) decided to implement Differentiated ReserveRequirement Ratio (DRRR) policy in the earthquake-stricken counties in Sichuan province in orderto help the reconstruction of these areas which suffered the big earthquake. The purpose of thisstudy is to examine the role of this DRRR policy on the disaster area. This paper compares theeffects of DRRR policy on the earthquake-stricken counties with that of the normal ReserveRequirement Ratio (RRR) on the other counties using panel data analysis during 2008-2011. Theresults confirm that this preferential DRRR policy can really quicken the recovery process in theearthquake-stricken counties. This DRRR policy reflects that the PBC starts to use differentiatedmonetary policy to guide credit funds flow to the area which government policy focus on. Monetarypolicy begins to play a role in adjusting and optimizing economic structure. Due to large regionaldisparity, the PBC can consider expand the application of this DRRR policy to more less developedregions to make a more coordinated regional economic development in China.Keywords: Differentiated Reserve Requirement Ratio; Earthquake-stricken Counties; Panel DataAnalysis.

Policy Attention

Abstract This article discusses the “uncoordinated” critique of the disaster recovery process and the current attempt to address the issue through the National Disaster Recovery Framework (NDRF). Scholars have identified that the topic of coordination in disaster recovery is one that needs policy attention and it is laudable that the federal government has provided such focused attention by way of the NDRF. Yet, it is also important to critically examine whether the NDRF’s proposed recovery coordination vision – the local disaster recovery manager – is a reasonable foundation upon which to address the issues of recovery processes nationwide. This article examines this issue by discussing the extent to which the NDRF recovery manager role is consistent with what the literature would suggest, the extent to which the NDRF role is needed, and the extent to which it is possible that the NDRF-depicted local role be fulfilled across the country. Implications for the vision set out in the NDRF and recommendations for future research are discussed in light of this analysis.
