Using the Distiller to direct the development of self-configuration software

Many storage systems have become so complex that that the system administrator's salary represents almost half of the total cost of ownership. One approach to reducing this cost is to develop storage systems that can configure and manage themselves. Unfortunately, our ability to develop such software has been hindered by a limited understanding of how workloads and storage systems interact. In earlier work we presented the design of the Distiller - our tool that automates the process of finding a workload's key performance-affecting attributes. In this paper, we distill three production workloads and show that the values of the chosen attributes contain information that will help self-configuring disk array to choose a reasonable prefetch length and RAID stripe unit size. We also discuss how the chosen attributes may help direct the development of algorithms that compute near-optimal prefetch lengths and stripe unit sizes.
Induced subgraphs of graphs with large chromatic number. XII. Distant stars

The Gyárfás‐Sumner conjecture asserts that if H is a tree then every graph with bounded clique number and very large chromatic number contains H as an induced subgraph. This is still open, although it has been proved for a few simple families of trees, including trees of radius two, some special trees of radius three, and subdivided stars. These trees all have the property that their vertices of degree more than two are clustered quite closely together. In this paper, we prove the conjecture for two families of trees which do not have this restriction. As special cases, these families contain all double‐ended brooms and two‐legged caterpillars.
SPOR YAPAN VE YAPMAYAN İLKÖĞRETİM ÖĞRENCİLERİNİN DEPRESYON DURUMLARININ BAZI DEĞİŞKENLERE GÖRE İNCELENMESİ

The purpose of this study is to analyse the depression states of elementary school students who are in the second grade at school and do sports or not according to some variables.There are 251 students who do sports (amateur athletes,play in school teams etc.) at city center elementary schools of Malatya and there are 251 students who do not sports in the analysing group so totally there are 502 students in the analysing group.Kolmogorov-Smirnov test has been applied to research datas and it has been seen that variables do not have a normal distribution at the end of test . So Mann Whitney U test has been used for the binary comparison and Kruskal Wallis test has been used for comparison more than two. α = 0.05 has been determined as signifance level . While it has been found that there is a difference statistically at signifance level betweeen depression points of students who do sports (X=12.44) and depression points of students who do not do sports (X=14.70); it has been found that there is not a difference at signifance level between branches and depression points of students who do sports.Additionally,it has been found that there is a difference statistically at signifance level between depression points of eighth grade students who do sports and eighth grade students who do not sports ; students who do sports and have 2001 TL ,3000 TL ,3001 TL and more family income status and students who do not do sports and have same family income status ; students who are 13 ,14 or over years old also do sports and students who are at same ages also do not do sports . According to research findings,it has been seen that elementary school students have generally low depression points and students who do sports have low depression points at signifance level if they are compared with other students who do not do sports . According to that result, elementary school students have been suggested to do sports to not have depression problems or to get over these depression problems.

The effects of slow- and fast-rhythm classical music on progressive cycling to voluntary physical exhaustion.

BACKGROUND To investigate, based on the parallel information processing model and arousal hypothesis, whether musical tempo and its manipulation during exercise affect the maximal workload (watts) achieved during progressive cycling. METHODS DESIGN repeated measures experiment that involved one control and four treatment conditions. SETTINGS the experiment was performed in a controlled laboratory environment. PARTICIPANTS twenty-four male and female volunteers, recruited from among a University population, were tested. INTERVENTION the data collection proceeded in five counterbalanced test-sessions that included control (C), slow music (SM), fast music (FM) slow to fast music (SFM) and fast to slow music (FSM) interventions. In the last two conditions, musical tempo was changed when the participant's maximal HR reserve has reached 70%. In all test-sessions, participants started to cycle at 50 watts and then the workload was increased in increments of 25 watts every minute until self-declared exhaustion. Maximal ergometer cycling was defined as the workload at the last completed minute of exercise. MEASURES workload, HR, and postexperimental ratings of test-session preferences were the dependent measures. RESULTS Significantly higher workload was accomplished in the SFM condition. No between-session differences were seen in HR. The results also yielded significantly better "efficiency", in terms of workload/HR reserve ratio, in the SFM session. PARTICIPANTS preferred the FM and SFM sessions more than the other sessions. CONCLUSIONS Switching to FM during progressive exercise results in the accomplishment of more work without proportional changes in HR. These effects may be due to distraction from fatigue and are, apparently, dependent on the attention capturing strength of the distracting stimulus.
Movilidad social y demanda de redistribución del ingreso en América Latina

Segun senalan Alesina y Angeletos (2005) y Alesina y Glaeser (2004), las preferencias en materia de redistribucion del ingreso varian sistematicamente entre las diversas regiones e inciden en la dimension del gobierno y la composicion de los gastos publicos. En este articulo se analiza la demanda redistributiva en America Latina, con particular atencion a los efectos de las expectativas de movilidad en la demanda de redistribucion. Los resultados sugieren el predominio de la demanda por interes personal y por consideraciones de justicia basadas en la desigualdad de oportunidades. Asimismo, se revela la importancia de la movilidad pasada y el rechazo de la hipotesis de la perspectiva de movilidad ascendente de Benabou y Ok (2001) con respecto a la region latinoamericana.
Improving Dynamic Invariant Saliency with Static Dataflow Analysis

Saliency of invariants reported by dynamic detection techniques tend to be poor. We present a prototype intra-procedural static analysis and invariant filtering system that improves reported invariant saliency by applying a data flow based admission criteria. While successful at reducing the number of nonsensical invariants reported, the current prototype is overly aggressive due to the limitations of intraprocedural data flow. Extension to inter-procedural analysis is nontrivial. Some of the challenges are discussed.
Letters to the Editor

I trust my letter to the editor about Fawcett and Alligood’s (2005) column is of interest. The topic intrigues me and as an aspirant nurse theorist I do spend time considering how nursing knowledge is generated and then disseminated. In the scholarly dialogue I found much to agree with and found some of the comments most stimulating. However the challenge even tension I experience, when I reflect upon nursing knowledge is the dichotomy between its espoused theory and its practice. In the dialogue you consider and speculate upon the nature of middle-range theories. You suggest that these theories may provide the insight and explanations nursing needs to address the dichotomy I allude to. The reason I suggest this is because middle-range theories seem to explore the practical world of nursing and perhaps it will be through the exploration of the practical world that nursing as a discipline will be realized. My following comments aim to explain my thinking further and why I think these theories will be the real influences on the advancement of nursing knowledge. Nightingale said that she used the word nursing for want of a better and she changed her mind frequently about the proper task of a nurse and who would make the best nurse. She thought that working-class girls, strictly supervised and properly motivated, would make the best nurses and cope best with what she admitted was often servile and repulsive hard work. The nurses’ task was to bring hygiene and health habits to the hospital and patients alike. However, the coming of Listerian, surgery, asepsis and the germ theory changed the nature of nursing. Physicians now needed nurses to work in collaboration in order to carry out medical treatment and surgery. Thereby, establishing the nurse as a handmaiden to medicine. Hence the quest to establish our own discipline based on prescribing and carrying out total care and putting the patient in the best position for nature to act on and not merely about carrying a treatment. Nightingale (as cited in Baly, 1991) stated that experience taught her that
Western and Eastern Principles and Globalised Bioethics

The title of the original symposium from which this paper is derived, “Western or Eastern Principles in a Globalised Bioethics? ”, makes a number of assumptions. First, it suggests that there are recognisable “Western” and “Eastern” principles of bioethics which can be easily identified; second, it suggests that these principles are different and separate from each other; third, it suggests that whether or not a global bioethics exists depends on the way such principles can or cannot be connected. This article will reject these assumptions as false. It argues that in fact there are not easily identifiable “Eastern” and “Western” principles of ethics which are mutually exclusive, nor are there ways of living based on these principles — which are fundamentally different from each other — which characterise lives in the “West” and the “East”, respectively. It argues that to present “Western” and “Eastern” principles as fundamentally different not only misrepresents the various traditions of ethics which can be drawn upon, but it is also dangerous, in that it divides the world into what are effectively two types of persons, as if we were not all human beings. In addition, it wrongly places the emphasis of the debate in the abstract realm of whether principles are compatible rather than in the realm of practice, where global bioethics is actually developing and becoming a reality. The article argues that to focus on the theoretical debate is also dangerous as it allows the practice of global bioethics to develop without robust critique and analysis. To permit this makes it more likely that the global bioethics which emerges is not representative of either East or West. Therefore, what we should do is to shift the debate away from questions about whether bioethics is possible in terms of combining principles and instead focus directly on practically shaping the emerging global bioethics.

A Hepatitis C Virus (HCV) Vaccine Comprising Envelope Glycoproteins gpE1/gpE2 Derived from a Single Isolate Elicits Broad Cross-Genotype Neutralizing Antibodies in Humans

Although a cure for HCV is on the near horizon, emerging drug cocktails will be expensive, associated with side-effects and resistance making a global vaccine an urgent priority given the estimated high incidence of infection around the world. Due to the highly heterogeneous nature of HCV, an effective HCV vaccine which could elicit broadly cross-neutralizing antibodies has represented a major challenge. In this study, we tested for the presence of cross-neutralizing antibodies in human volunteers who were immunized with recombinant glycoproteins gpE1/gpE2 derived from a single HCV strain (HCV1 of genotype 1a). Cross neutralization was tested in Huh-7.5 human hepatoma cell cultures using infectious recombinant HCV (HCVcc) expressing structural proteins of heterologous HCV strains from all known major genotypes, 1–7. Vaccination induced significant neutralizing antibodies against heterologous HCV genotype 1a virus which represents the most common genotype in North America. Of the 16 vaccinees tested, 3 were selected on the basis of strong 1a virus neutralization for testing of broad cross-neutralizing responses. At least 1 vaccinee was shown to elicit broad cross-neutralization against all HCV genotypes. Although observed in only a minority of vaccinees, our results prove the key concept that a vaccine derived from a single strain of HCV can elicit broad cross-neutralizing antibodies against all known major genotypes of HCV and provide considerable encouragement for the further development of a human vaccine against this common, global pathogen.
Ensuring Robust Analysis

Marxan is a useful tool, but to get robust results requires a significant investment in setting up the problem, calibrating the algorithm, and running sensitivity tests on the results. This chapter provides guidance in some of the necessary steps in that process. For a given solution, check that it is feasible (meets all targets). Each time a change is made to the problem being solved, Marxan's other parameters may need re‐adjustment. Evaluate the quality of solutions generated in terms of the costs, objective function, and levels of protection provided. Test how sensitive the results are to changes in Marxan parameters, input data (especially uncertain data) and conservation targets. Following these steps will develop a much better understanding of the problem, how the various parameters and features affect it, and the robustness of the solutions generated. The objective of the optimiser in Marxan is to " select some of everything, for the lowest cost " (see Box 1.1). Calibrating and fine‐tuning Marxan to achieve this stated goal of " lowest cost " while generating a range of solutions is the subject of this chapter. Other chapters have covered some of the issues surrounding the process of translating broad policy goals into a mathematical problem statement, and hence parameters, that Marxan can work on. This chapter will address the various user settings, calibration procedures, and sensitivity testing necessary to ensure Marxan is producing a range of near‐optimal, " lowest cost " solutions to each variant of the specified problem. Once the initial data are assembled, the recommended solution process iterates through multiple steps (Figure 8.1). The first step is to prepare initial input files for calibration (setting planning unit costs, the amount of each conservation feature in each planning unit, and a target for each conservation feature). The decisions made in setting up the planning unit costs, etc. (see Section 8.2.2 ‐ Planning unit cost) can strongly influence Chapter 8: Ensuring Robust Analysis 75
Transactions on Dependable and Secure Computing Mobiflage: Deniable Storage Encryption for Mobile Devices

—Data confidentiality can be effectively preserved through encryption. In certain situations, this is inadequate, as users may be coerced into disclosing their decryption keys. Steganographic techniques and deniable encryption algorithms have been devised to hide the very existence of encrypted data. We examine the feasibility and efficacy of deniable encryption for mobile devices. To address obstacles that can compromise plausibly deniable encryption (PDE) in a mobile environment, we design a system called Mobiflage. Mobiflage enables PDE on mobile devices by hiding encrypted volumes within random data in a devices free storage space. We leverage lessons learned from deniable encryption in the desktop environment, and design new countermeasures for threats specific to mobile systems. We provide two implementations for the Android OS, to assess the feasibility and performance of Mobiflage on different hardware profiles. MF-SD is designed for use on devices with FAT32 removable SD cards. Our MF-MTP variant supports devices that instead share a single internal partition for both apps and user accessible data. MF-MTP leverages certain Ext4 file system mechanisms and uses an adjusted data-block allocator. These new techniques for storing hidden volumes in Ext4 file systems can also be applied to other file systems to enable deniable encryption for desktop OSes and other mobile platforms.
A PSICOLOGIA COGNITIVA E MEDIAÇÃO INFORMACIONAL COMO FACILITADORAS DE NOVAS ATITUDES NO COMPORTAMENTO ORGANIZACIONAL

O presente artigo fundamenta a importância da Psicologia Cognitiva e a mediacao informacional no âmbito das organizacoes. O avanco tecnologico fez com que processos de gestao, baseados no taylorismo e fordismo, ja nao respondam as necessidades organizacionais atuais, que sao ambientes complexos. Uma nova perspectiva de acao e alteracao no arcabouco organizacional pode ser a Psicologia cognitiva, que busca a otimizacao de seus processos atraves dos modelos mentais. Essa otimizacao e superacao das inumeras dificuldades que podem estar presentes, tendem a ser uma realidade. Contudo, nao se pode alcancar otimizacao, sucesso organizacional em detrimento do bem-estar do sujeito. Espera-se que a Psicologia Cognitiva possa contribuir para com o novo patamar organizacional.
Intelligent Smart Bait Fishing: A New Mobile App Business Model

New Zealand has a long history of fishing, being an island nation. Almost 20% of the population favors recreational fishing. Knowing the best fishing spots and type of bait, in addition to the right time of day, are the keys to the success of catches. Having this information on a mobile app would be useful to anglers. There are many fishing apps available from the iTunes app market. However, after investigating the existing iTunes app store, there is no highly integrated app with social capability and fishing functionality available. This article proposes a new fishing mobile application that adopts Apple SWIFT technology, which supports the Windows and Linux platforms, to ensure its future sustainable development. Social network capability of this app includes a bite-time check, fishing trip arrangement, statistics, and a fishing knowledge base. By using the proposed app, the anglers can share their fishing activity with family and friends by simply synchronizing the post to social media. Moreover, government or non-government agencies can share the movement and distribution of marine wildlife by analyzing the available information collected by the app.
Two Convergence Problems for Robots on Graphs

The class of robot convergence tasks has been shown to capture fundamental aspects of fault-tolerant computability. A set of asynchronous robots that may fail by crashing, start from unknown places in some given space, and have to move towards positions close to each other. In this article, we study the case where the space is uni-dimensional, modeled as a graph G. In graph convergence, robots have to end up on one or two vertices of the same edge. We consider also a variant of robot convergence on graphs, edge covering, where additionally it is required that not all robots end up on the same vertex. Remarkably, these two similar problems have very different computability properties, related to orthogonal fundamental issues of distributed computations: agreement and symmetry breaking. We characterize the graphs on which each of these problems is solvable, and give optimal time algorithms for the solvable cases. Although the results can be derived from known general topology theorems, the presentation serves as a self-contained introduction to the topology approach to distributed computing, and yields concrete algorithms and impossibility results.
The Src SH3 Domain Is Required for DNA Synthesis Induced by Platelet-derived Growth Factor and Epidermal Growth Factor*

The Src family of protein tyrosine kinases has been implicated in the response of cells to platelet-derived growth factor (PDGF) or epidermal growth factor (EGF). We recently described a microinjection approach that we used to demonstrate that kinase activity of Src family members is required for PDGF- and EGF-induced S-phase entry of fibroblasts. We have now used this approach to ask whether a functional SH3 domain of Src is required to transduce the mitogenic signal upon PDGF or EGF stimulation. Microinjection of plasmids encoding Src mutants lacking the SH3 domain (SrcΔSH3) or point-mutated within the ligand binding surface of the SH3 domain, but with intact kinase domains, inhibited the mitogenic effect of PDGF and EGF in fibroblasts. SrcΔSH3 could still associate with the PDGF receptor, suggesting that the inhibitory effect of the Src SH3 mutants was brought about by a failure of the PDGF receptor·SrcΔSH3 complex to relay the mitogenic signal further downstream. Chimeric molecules in which the Src SH3 domain was replaced with that of spectrin or Lck also blocked PDGF-induced DNA synthesis, whereas a chimera containing the Fyn SH3 domain did not. These data suggest that the Src or Fyn SH3 domain is required either for correct substrate selection or to recruit other proteins to the PDGF receptor.
The Global Response of Nostoc punctiforme ATCC 29133 to UVA Stress, Assessed in a Temporal DNA Microarray Study

Cyanobacteria in nature are exposed not only to the visible spectrum of sunlight but also to its harmful ultraviolet components (UVA and UVB). We used Nostoc punctiforme ATCC 29133 as a model to study the UVA response by analyzing global gene expression patterns using genomic microarrays. UVA exposure resulted in the statistically detectable differential expression of 573 genes of the 6903 that were probed, compared with that of the control cultures. Of those genes, 473 were up‐regulated, while only 100 were down‐regulated. Many of the down‐regulated genes were involved in photosynthetic pigment biosynthesis, indicating a significant shift in this metabolism. As expected, we detected the up‐regulation of genes encoding antioxidant enzymes and the sunscreen, scytonemin. However, a majority of the up‐regulated genes, 47%, were unassignable bioinformatically to known functional categories, suggesting that the UVA stress response is not well understood. Interestingly, the most dramatic up‐regulation involved several contiguous genes of unassigned metabolism on plasmid A. This is the first global UVA stress response analysis of any phototrophic microorganism and the differential expression of 8% of the genes of the Nostoc genome indicates that adaptation to UVA in Nostoc has been an evolutionary force of significance.
Properties of medium-density fiberboard related to hardwood specific gravity

Boards of acceptable quality were made from barky material, pressure-refined from 14 species of southern hardwoods. Static bending and tensile properties (parallel to surface) of specimens were negatively correlated to stem specific gravity (wood plus bark), chip bulk density, and fiber bulk density. Bending and tensile properties increased with increasing densification ratio, but the rate of increase was much less than published information for flake board from 9 of the 14 species. Results for internal bond strength were inconclusive. By regression analysis, internal bond was independent of stem specific gravity, chip bulk density, and fiber bulk density. Measurements of fiber pH and Bauer-McNett screen classification also failed to explain the wide variation in internal bond.
