Multi-objective Hadoop Configuration Optimization Using Steady-State NSGA-II

Hadoop configuration optimization is very challenging because of the complexity of its framework. And optimized Hadoop parameter configuration settings depend significantly on the performance of MapReduce applications in the cluster. Although much research has been conducted on Hadoop parameters configuration optimization, configuring its resource setting parameters to minimize the execution time of MapReduce jobs in clusters still needs a lot of continuing researches. Further, determining the type of machine instances that should be used to minimize the resource usage cost for executing applications in clusters is also difficult. This paper addresses these problems by optimizing the instance resource usage and execution time of MapReduce tasks using a multi-objective steady-state Non-dominated Sorting Genetic Algorithm II (ssNSGA-II) approach. In this approach, the instance resource usage cost of MapReduce tasks is calculated based on the cost of machine instance types and the number of machine instances in the Hadoop cluster. The optimized configuration is identified by selecting an optimal setting that satisfies two objective functions associated with instance resource usage and execution time minimization, from Pareto optimal front solutions. Although dynamic machine instance type is considered within the search process in our system, dynamic cluster size is out of consideration and intended to be carried out in our future. Experiments conducting using workloads from the HiBench benchmark on a high specification 6-node Hadoop cluster verify the efficacy of our proposed approach.
Philosophy in the Flesh: The Embodied Mind and Dramatherapy

I ask a reader to look at these sentences. They describe a familiar experience of most, if not all writers. What is of interest to me here, however, are those words I have marked in bold typeface. I wish to draw your attention to the physicality of those words I am poised physically and metaphorically; waiting for creative inspiration while also ‘inspiring’ (i.e. taking an inward breath); trying to squeeze out the words like play dough from my hands; the pain of writing. These are words of and about the body used metaphorically to express subjective experience. It seems that, not surprisingly since we live in and through our bodies, the use of ‘body metaphors’ to describe our experience is extremely common and as I will later discuss, it is often difficult to find means to describe subjective experience without their use. In this article I want to examine this closely and in doing so I will be relying heavily on the work of George Lakoff and Mark Johnson (1999). Their ideas about what they call ‘the embodied mind’ are, I will suggest, highly relevant to dramatherapy practice.
Numerical Simulations of Finite Dimensional Spin Glasses Show a Mean Field like Behavior

I discuss results from numerical simulations of finite dimensional spin glass models, and show that they show all signatures of a mean field like behavior, basically coinciding with the one of the Parisi solution. I discuss the Binder cumulant, the probability distribution of the order parameter, the non self-averaging behavior. The determination of correlation function and of spatially blocked observables quantities helps in qualifying the behavior of the system.
Paravertebral Block for Analgesia After Pediatric Thoracic Surgery

Children with pectus excavatum and other chest wall deformities present to pediatric centers for reconstructive surgery. The Nuss operation involves positioning a metal bar under the sternum to exert anterior pressure. Although the Nuss operation is regarded as “limited access” or “minimally invasive,” pain after the operation is typically more severe than after open repairs such as the Ravitch operation. In the current issue of Regional Anesthesia and Pain Medicine, Qi and colleagues report on a randomized, observer-blinded trial of bilateral single-shot paravertebral nerve block (PVNB) for analgesia after pediatric Nuss operations. In the discussion that follows, PVNB will be used inclusively for both single-shot blocks and infusions, unless otherwise stated. A recent survey of pediatric centers performing Nuss procedures reported that 91% of centers used thoracic epidural analgesia (TEA) for at least some of their patients. Outcomes have varied among studies, but, overall, TEA seems more effective than intravenous patient-controlled analgesia (PCA) for Nuss procedures. Pediatric TEA has an excellent track record for safety, as evidenced by reports from registries. Recent case reports identified a small number of cases of permanent neurologic deficits in children after TEA for Nuss procedures. There is an absence of evidence pointing to negligence, malpractice, or direct spinal cord trauma. In adult regional anesthetic practice, there has been widespread adoption of ultrasound guidance for PVNB for postthoracotomy analgesia, and there is a spirited debate over the relative efficacy, effectiveness, noninferiority, safety, and side effect profiles of PVNB compared with TEA. Of note, almost all previous comparisons between PVNB and TEA involve unilateral blocks for unilateral thoracic surgery, whereas the Nuss procedure requires bilateral coverage. Pediatric publications on PVNB extend for more than 20 years. During the past 5 years, PVNB is being performed in selected pediatric centers using ultrasound guidance. The total number of patients in pediatric case series, with or without ultrasound guidance, remains small. In the trial by Qi and colleagues, children receiving single-shot PVNB showed substantial reductions in pain scores and supplemental opioid use compared with controls who received no regional analgesia, and they displayed fewer postoperative behavioral disturbances. At first glance, these differences seem surprisingly robust and impressive. This study can be commended in several respects and should evoke caution or criticism in others.
Cognitive Factors in Persistent versus Recovered Post-Traumatic Stress Disorder after Physical or Sexual Assault: A Pilot Study

Cognitive models have linked individual differences in the appraisal of traumatic events and their sequelae to the persistence of post-traumatic stress disorder (PTSD). A pilot study investigated this proposal with victims of assault. Eleven assault victims suffering from persistent PTSD and 9 victims who had recovered from PTSD were interviewed retrospectively and compared on potentially relevant cognitive factors. Groups were comparable in terms of characteristics of the assault, gender, age, and initial PTSD severity. Participants with persistent PTSD were less likely than those who had recovered to have engaged in mental planning during the assault and more likely to have experienced mental defeat, and to indicate negative appraisals of their actions during the assault, of others' reactions after the assault, and of their initial PTSD symptoms. They were also more likely to indicate global negative beliefs concerning their perception of themselves, their world or their future. These cognitive factors may maintain PTSD symptoms either directly or by motivating the individual to engage in behaviour that prevents change.
The challenge of virginia banks: an evaluation of named entity analysis in a 19th-century newspaper collection

This paper evaluates automatic extraction of ten named entity classes from a 19th century newspaper, the Civil War years of the Richmond Times Dispatch, digitized with IMLS support by the University of Richmond. This paper analyzes success with ten categories of entities prominent in these newspapers and the particular problems that these classes of named entities raise. Personal and place names are familiar but some more important categories (such as ship names and military units) illustrate some of the challenges that named entity identification confronts as it evolves into a fundamental tool not only for automatic metadata generation but also for searching and browsing as well. We conclude by suggesting the kinds of knowledge sources that digital libraries need to assemble as part of their machine readable reference collections to support named entity identification as a core service
In Vivo Development of Brain Phosphocreatine in Normal and Creatine‐Treated Rabbit Pups

Abstract : To study the effects of creatine (Cr) on brain energy metabolism and on hypoxia‐induced seizures, 5‐to 30‐day‐old rabbit pups were given subcutaneous Cr (3 g/kg) for 3 days before exposure to 4% O2 for 8 min. In saline‐treated controls, hypoxic seizures were most frequent at 15 days (80% of pups) and 20 days (60%) of age. Seizures were prevented at 15 days and reduced 60% at 20 days in Cr‐treated pups. In surface coil‐localized brain 31P nuclear magnetic resonance spectra, with signal from both cerebral gray (GM) and white (WM) matter, the phosphocreatine (PCr)/nucleoside triphosphate (NTP) ratio doubled between 5 and 30 days of age in controls. In all Cr‐injected pups, brain PCr/NTP increased to values seen in 30‐day‐old controls. When spectra were acquired in predominantly GM and WM slices in vivo, the PCr/NTP ratio was very low in GM at 5 days but reached adult levels by 15 days in controls. In WM, the ratio increased steadily from 5 to 30 days of age. In Cr‐injected pups, PCr/NTP increased to mature levels in WM and in GM at all ages. In conclusion, hypoxic seizures occur midway in the time course of brain PCr/NTP increase in rabbit pups as previously described in rat pups. In both altricial pups, systemic Cr increases brain PCr/NTP ratio and prevents hypoxic seizures. These results suggest that mature levels of PCr and/or Cr in brain limit EEG activation either directly or indirectly by preventing hypoxic metabolic changes.
Motivations for media sharing among mobile phone users

Mobile media sharing has become an increasingly commonly activity. Using a dairy study, we investigated motivations behind mobile media sharing. Participants maintained a month-long diary, documenting their media sharing activities. Post-study interviews were also conducted to elicit additional information. Results suggest a range of motivational factors for media sharing behavior. These include personal and social influences. Participants were also more inclined to share photos than with any other media due to cost and transmission time considerations. Implications of our work are discussed.
Genome-Wide Copy Number Variant Analysis in Inbred Chickens Lines With Different Susceptibility to Marek’s Disease

Breeding of genetically resistant chickens to Marek’s disease (MD) is a vital strategy to poultry health. To find the markers underlying the genetic resistance to MD, copy number variation (CNV) was examined in inbred MD-resistant and -susceptible chicken lines. A total of 45 CNVs were found in four lines of chickens, and 28 were potentially involved in immune response and cell proliferation, etc. Importantly, two CNVs related with MD resistance were transmitted to descendent recombinant congenic lines that differ in susceptibility to MD. Our findings may lead to better strategies for genetic improvement of disease resistance in poultry.
Deployment of wireless sensor networks for biomedical applications

Biomedical wireless sensor networks are a key technology to enable the development of new healthcare services and/or applications, reducing costs and improving the citizen's quality of life. However, since they deal with health data, such networks should implement mechanisms to enforce high levels of quality of service. In most cases, the sensor nodes that form such networks are small and battery powered, and these extra quality of service mechanisms mean significant lifetime reduction due to the extra energy consumption. The network lifetime is thus a relevant feature to ensure the quality of service requirements. In order to maximise the network lifetime and its ability to offer the required quality of service new strategies are needed to increase the energy efficiency and balance in the network. The focus of this work is the use of the remaining energy in each node combined with information on the reliability of the wireless links, as a metric to form reliable and energy-aware routes throughout the network. This paper presents and discusses an implementation of a lifetime-extending methodology based on energy-aware routing and relay nodes simulated for three different logical topologies. Our conclusion is that such methodology may increase the network lifetime an average of 45%.
Signifying Voices: Reading the “Adam Smith Problem”

The “Adam Smith problem” has traditionally been concerned with the issue of authorial integrity: the issue of how a single author, Adam Smith, could have written two such apparently dissimilar, even contradictory, works as The Theory of Moral Sentiments (TMS) and The Wealth of Nations (WN). As the problem to be resolved was the single authorial origin of two such works, the perceived incompatibilities between them were explained in terms of Smith's intellectual biography – for example, Smith's travels to France, Smith's meetings with the physiocrats, or the mental incapacities of an aging man. The current consensus is that the Adam Smith problem is a “pseudo problem” and that Smith's works represent a unified project, but the same reference to authorial origins now provides thr opposite claim that “the same man” wrote both books (Raphael and Macfie, 1976, p. 20). Here the postulate of authorial integrity, “of stable integrated character, not subject to deep intellectual doubts or fissures” provides an assurance that such a man is unlikely to have written two entirely different books (Macfie, 1967, p. 76), an assurance underwritten by a coherent authorial intentionality that guarantees the consistency of the two works.
An Analysis of Suicide Rates among Occupational Categories

The correlation between the NORC prestige scale of 1947 with 1950 suicide rates is extremely low for thirty-six specific occupations. The low correlation calls into question the findings of previous studies which employed gross occupational categories and impressionistic prestige rankings. The results indicate that client dependency and two multivariate models, status inconsistency and distributive justice, deserve further exploration in predicting suicide rates for occupations.
The effect of mobile station rotation on a correlation model for microcellular environments

This paper studies the effect of rotation of a mobile station (MS) on the cross-correlation function (CCF) derived for a microcellular isotropic wave propagation environment with enough number of scatterers. The statistical model characterizes the propagation media when the MS rotates with a constant angular velocity around an axis perpendicular to the azimuthal plane, and moves with a constant velocity on the azimuthal plane in an arbitrary direction. The moving MS, with a constant speed, produces the conventional linear Doppler while the rotating MS introduces angular Doppler. The research shows that the rotation of the MS results in a non-stationary random process as the CCF. The only exception in which the result follows a stationary function is a narrow-band communication system, when either the MS angular velocity or the MS speed is zero.
The Association of Flap Endonuclease 1 Genotypes with the Risk of Childhood Leukemia.

AIM Flap endonuclease 1 (FEN1) is one of the most important proteins in maintaining genome stability and preventing carcinogenesis. In recent years, the contribution of two variants of FEN1, rs174538 and rs4246215, regarding cancer risk have been investigated in lung, breast, liver, esophageal, gastric, colorectal cancer and glioma. However, it has not been revealed whether rs174538 and rs4246215 are associated with leukemia. Therefore, in the present study we aimed to evaluate the contribution of these genotypic polymorphisms in FEN1 to childhood acute lymphoblastic leukemia (ALL) risk in Taiwan. MATERIALS AND METHODS In total, 266 patients with childhood ALL and an equal number of recruited non-cancer controls were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). RESULTS The FEN1 rs174538 genotype, but not rs4246215, was differently distributed between childhood ALL and control groups. The AG and AA of FEN1 rs174538 genotypes were significantly less frequently found in childhood ALL patients than in controls (odds ratio [OR]=0.68 and 0.48, 95%confidence intervals [CI]=0.47-0.98 and 0.24-0.82, respectively). As for gender, boys carrying the FEN1 rs174538 AG or AA genotype conferred lower ORs of 0.55 and 0.36 (95%CI=0.33-0.91 and 0.18-0.73, p=0.0053) for childhood ALL. Regarding age, those equal to or greater than 3.5 years of age at onset carrying the FEN1 rs174538 AG or AA genotype were of lower risk (ORs=0.53 and 0.32, 95%CI=0.31-0.90 and 0.15-0.70, p=0.0042). CONCLUSION The FEN1 rs174538 A allele is a protective biomarker for childhood ALL and this association is more significant in males and in patients at onset age of 3.5 years or older.
Enabling software defined networking experiments in networked critical infrastructures

Nowadays, the fact that Networked Critical Infrastructures (NCI), e.g., power plants, water plants, oil and gas distribution infrastructures, and electricity grids, are targeted by significant cyber threats is well known. Nevertheless, recent research has shown that specific characteristics of NCI can be exploited in the enabling of more efficient mitigation techniques, while novel techniques from the field of IP networks can bring significant advantages. In this paper we explore the interconnection of NCI communication infrastructures with Software Defined Networking (SDN)-enabled network topologies. SDN provides the means to create virtual networking services and to implement global networking decisions. It relies on OpenFlow to enable communication with remote devices and has been recently categorized as the “Next Big Technology”, which will revolutionize the way decisions are implemented in switches and routers. Therefore, the paper documents the first steps towards enabling an SDN-NCI and presents the impact of a Denial of Service experiment over traffic resulting from an XBee sensor network which is routed across an emulated SDN network.
Identifying good opportunities to act: Implementation intentions and cue discrimination

Forming an implementation intention (‘If I encounter situation X, then I'll perform behaviour Y! ’) is thought to increase the likelihood that the person will detect a good opportunity to act. Experiment 1 found support for this hypothesis in a novel context where detection of the specified cue was very difficult. Experiments 2 and 3 extended existing paradigms to test whether this improved cue detection has costs in terms of increased false positives and/or slower responses to ambiguous stimuli. This hypothesis was not supported. Forming an implementation intention led to more accurate (Experiment 2) and faster (Experiment 3) responses to the specified cue without compromising responses to non-relevant, or ambiguous, stimuli. Overall, the findings suggest that forming an implementation intention is an effective self-regulatory tool because the specified cues are discriminated swiftly and with precision.

General-Purpose Assertions for Data Structures

We first present a general purpose assertion language for expressing properties of data structures. Its predicates model the heap as an array and pointers as variables over memory indices. The key point is that these predicates can be user-defined in a general manner using recursive rules. Consequently, these predicates can be defined to an arbitrary level of expressiveness, ranging from low-level properties of the memory allocation policy, to abstract properties of complex data structures such as AVL trees. We then present a proof method for these predicates. First, both the assertion predicates and the program semantics are represented in the framework of Constraint Logic Programming. Then we present proof rules, which include a novel use of coinduction, which allow for the consistent reasoning about both recursion in assertions and loops in programs. We finally argue that this proof methodology is intuitive and expressive, and that the proof method is amenable to a practical implementation.
How approaches to teaching are affected by discipline and teaching context

Two related studies are reported in this article. The first aimed to analyse how academic discipline is related to university teachers’ approaches to teaching. The second explored the effects of teaching context on approaches to teaching. The participants of the first study were 204 teachers from the University of Helsinki and the Helsinki School of Economics and Business Administration and 136 teachers from the University of Oxford and Oxford Brookes University who returned university teaching inventories. Thus, altogether there were 340 teachers from a variety of disciplines in Finland and the UK. The second study involved only the Finnish sample. The results showed that there was systematic variation in both student‐ and teacher‐focused dimensions of approaches to teaching across disciplines and across teaching contexts. These results confirm the relational nature of teachers’ approaches to teaching and illustrate the need, in using inventories such as the Approaches to Teaching Inventory, to be explicit about the context.

We present ROSAT HRI X-ray observations of all the galaxy clusters in the Le F\`evre et al. arc survey sample in order to study the spatial distribution of the intra-cluster medium, and examine the expected number of giant luminous arcs for the sample using two spherically symmetric lens models constrained by our X-ray data.
Psychological Hardiness Predicts Success in a Norwegian Armed Forces Border Patrol Selection Course

The present study investigates the effects of psychological hardiness and successful completion of a rigorous 250‐km ski march over 9 days in Arctic winter conditions. This ski march is the final portion of a selection program for border rangers in the Norwegian Armed Forces. Study participants were N = 178 soldiers with a mean age of 19.9 years (range 18–23). Hierarchical regression results showed that successful completion of the ski march was predicted by total hardiness scores, after controlling for nutrition factors, physical fitness and sensation seeking. A second hierarchical regression found that the commitment facet of hardiness was the most significant predictor of ski march success, again controlling for nutrition, physical fitness and sensation seeking. Analyses of daily participant surveys showed that the high commitment group reported the highest levels of positive daily coping, and also evaluated their performance more positively. This group also showed increasingly positive self‐evaluations as the exercise went on. Together, these results indicate that hardiness commitment is a key factor influencing performance in a rigorous and stressful endurance task requiring sustained effort, perhaps by enhancing active coping skills and self‐efficacy beliefs.
