Capturing mobile security policies precisely

The security policies of mobile devices that describe how we should use these devices are often informally specified. Users have preferences for some apps over others. Some users may avoid apps which can access large amounts of their personal data, whilst others may not care. A user is unlikely to write down these policies or describe them using a formal policy language. This is unfortunate as without a formal description of the policy we cannot precisely reason about them. We cannot help users to pick the apps they want if we cannot describe their policies. Companies have mobile security policies that define how an employee should use smart phone devices and tablet computers from home at work. A company might describe the policy in a natural language document for employees to read and agree to. They might also use some software installed on employee’s devices to enforce the company rules. Without a link between the specification of the policy in the natural language document and the implementation of the policy with the tool, understanding how they are related can be hard. This thesis looks at developing an authorisation logic, called AppPAL, to capture the informal security policies of the mobile ecosystem, which we define as the interactions surrounding the use of mobile devices in a particular setting. This includes the policies of the users, the devices, the app stores, and the environments the users bring the devices into. Whilst earlier work has looked on checking and enforcing policies with low-level controls, this work aims to capture these informal policy’s intents and the trust relationships within them separating the policy specification from its enforcement. This allows us to analyse the informal policies precisely, and reason about how they are used. We show how AppPAL instantiates SecPAL, a policy language designed for access control in distributed environments. We describe AppPAL’s implementation as an authorisation logic for mobile ecosystems. We show how we can check AppPAL policies for common errors. Using AppPAL we show that policies describing users privacy preferences do not seem to match the apps users install. We explore the di↵erences between app stores and how to create new ones based on policy. We look at five BYOD policies and discover previously unexamined idioms within them. This suggests aspects of BYOD policies not managed by current BYOD tools.
Suicidal Ideation and Associated Factors among School-Going Adolescents in Thailand

The aim of this study was to estimate the prevalence and identify associations between suicidal ideation and indicators of psychosocial distress and social-environmental factors in Thai adolescents. Using data from the Thailand Global School-Based Student Health Survey (GSHS) 2008, we assessed the prevalence of suicidal ideation and its associated factors among adolescents (N = 2,758). Overall the prevalence of suicidal ideation in the past 12 months was 8.8% (9.9% males and 7.7% females). Variables influenced the suicidal ideation in multivariable analysis were sadness (Odds Ratio = OR: 6.03; 95% Confidence Interval = CI (3.00–12.14), lack of parental attachment (OR = 2.26, CI = 1.09–4.67), current alcohol use (OR = 2.32, 1.21–4.44), and ever having had sexual intercourse (OR = 4.16, CI = 3.40–7.68). Psychosocial, health-risk behaviours and lack of protective factors appear to effect suicidal ideation in this youth population.
2006 X-Ray / Ultraviolet Observing Campaign of the Markarian 279 Active Galactic Nucleus Outflow : a close look at the absorbing / emitting gas with

We present low-resolution ultraviolet spectra of 14 low redshift (zem . 0.8) quasars observed with HST/STIS as part of a Snap project to understand the relationship between quasar outflows and luminosity. By design, all observations cover the C IV emission line. Nine of the quasars are from the Hamburg-ESO catalog, three are from the Palomar-Green catalog, and one is from the Parkes catalog. The sample contains a few interesting quasars including two broad absorption line (BAL) quasars (HE 01433535, HE0436-2614), one quasar with a mini-BAL (HE 1105-0746), and one quasar with associated narrow absorption (HE 0409-5004). These BAL quasars are among the brightest known (though not the most luminous) since they lie at zem < 0.8. We compare the properties of these BAL quasars to the zem < 0.5 Palomar-Green and zem > 1.4 Large Bright Quasar samples. By design, our objects sample luminosities in between these two surveys, and our four absorbed objects are consistent with the v ∼ L0.62 relation derived by Laor & Brandt (2002). Another quasar, HE0441-2826, contains extremely weak emission lines and our spectrum is consistent with a simple powerlaw continuum. The quasar is radio-loud, but has a steep spectral index and a lobedominated morphology, which argues against it being a blazar. The unusual spectrum of this quasar resembles the spectra of the quasars PG1407+265, SDSSJ1136+0242, and PKS1004+13 for which several possible explanations have been entertained.

ON SPECTRAL RADIUS ALGEBRAS

We show how one can associate a Hermitian operator P to every operator A ,a nd we prove that the invertibility properties of P imply the non-transitivity and density of the spectral radius algebra associated to A. Inthe finite dimensional case we give a complete characterization of these algebras in terms of P. In addition, we show that in the finite dimensional case, the spectral radius algebra always properly contains the commutant of A.
Letter to the Editor

Thank you for recognizing the merit of this study. Your comments are well received. In this retrospective study of 34 000 adolescents, we chose the Skyndex 1 caliper because it was one of the only calipers at that time that would give us a quick body fat percentage reading. It came programmed with the Jackson-Pollock formula, which is recommended by the American College of Sports Medicine. We are aware that there is some question regarding its use on adolescents. For the measurement taken, the caliper was set to the lowest possible age group (18 years). Because the caliper performed the calculation, the 3 individual skinfold measurements were not recorded, only the final calculation of body fat percentage was recorded; therefore, recalculation using the existing data is impossible. We read the report of Valizadeh and associates in which 3 equations (Brozek, Slaughter, and Jackson-Pollock) were used to calculate body fat percentage in 45 Iranian adolescents. When the formulas were compared, it is interesting to note that although the Jackson-Pollock formula underestimated body fat percentage and the Slaughter et al equation overestimated body fat percentage, the Brozek prediction equation held more promise for estimating body fat percentage. We would also refer readers to the article by Lohman in Exercise and Sports Science Reviews. In this article, there is reference to the fact that, in both males and females, large deviations in skinfold distribution with growth are not apparent and that chemical maturity occurs between 15 and 18 years of age. By this criterion, 69% of the student athletes in our study were at or near chemical maturity. In the report of the study by Valizadeh et al, the authors indicated the need for further studies. We also believe that our study, along with others, has merit. However, we hope the methods used for predicting body fat will continue to be the subject of further research.
C-reactive protein--to screen or not to screen?

Prediction is very difficult, especially about the future. — Niels Bohr More than 20 years ago, 246 risk factors for coronary heart disease (CHD) had already been identified, and the number continues to grow.1 Advances in genomics and proteomics will provide even more candidate markers to consider for routine assessment in practice. Risk stratification is important because information about the probability of a cardiovascular event in the future can help target therapy and resources to those most likely to benefit. Of the several hundred known correlates of CHD, only a handful have had the staying power to be recommended for .
When Does Partitioned Pricing Lead to More Favorable Consumer Preferences?: Meta-Analytic Evidence:

ABSTRACT There has been contradictory evidence regarding the impact of partitioned pricing. Research has shown that partitioning a price into multiple components can result in more favorable preferences due to a lower recalled price, or less favorable preferences due to unfavorable surcharge evaluations. To explain these divergent effects, the authors examine the role of price presentation moderators, reflecting how managers convey the prices to consumers (e.g., is the total price present or absent? ), magnitude moderators, reflecting the actual prices charged (e.g., what is the surcharge magnitude? ), and contextual moderators, reflecting non-price transaction characteristics (e.g., is the product category hedonic or utilitarian? ). A meta-analysis of 17 years of partitioned pricing research examining 149 observations in 27 papers (N = 12,878) suggests that consumers respond more favorably to partitioned pricing than all-inclusive pricing when the total price is absent, as the price level increases, when th.
The potential of big housing data: an application to the Italian real-estate market

We present a new dataset of housing sales advertisements (ads) taken from Immobiliare.it, a popular online portal for real estate services in Italy. This dataset fills a big gap in Italian housing market statistics, namely the absence of detailed physical characteristics for houses sold. The granularity of online data also makes possible timely analyses at a very detailed geographical level. We first address the main problem of the dataset, i.e. the mismatch between ads and actual housing units - agencies have incentives for posting multiple ads for the same unit. We correct this distortion by using machine learning tools and provide evidence about its quantitative relevance. We then show that the information from this dataset is consistent with existing official statistical sources. Finally, we present some unique applications for these data. For example, we provide first evidence at the Italian level that online interest in a particular area is a leading indicator of prices. Our work is a concrete example of the potential of large user-generated online databases for institutional applications.
An Abundant mRNA of the Embryonic Brain Persists at a High Level in Cerebellum, Hippocampus and Olfactory Bulb During Adulthood

In order to identify markers of the two neuronal populations which are successively involved in forebrain ontogenesis, we performed a differential screening of a murine cDNA library with two radiolabelled probes corresponding to striatal mRNAs extracted at embryonic day (E) 17 and E20, i.e. before and after the invasion of the striatum by the late‐born matrix neurons. One of the selected clones, the 3.1 cDNA, corresponds to a very abundant embryonic neuronal transcript enriched in the germinal zones at E17 and in superficial cortical layers and striatum at E20, suggesting that it is expressed mainly in neurons belonging to a late migration wave. During adulthood, it persists at a high level in the granular layer of the cerebellum, the hippocampus and the olfactory bulb, which are the sites of postnatal neurogenesis and intense synaptic plasticity. This 2000 base RNA is enriched in polysomal fractions and encodes a small putative 68 amino acid polypeptide which is conserved in mouse and man.

Research on Availability of Satellite Images Based on Immune Feedback Learning Fuzzy Neural Network

In this paper, we propose a fuzzy neural network based on immune feedback learning¿FNNBIFL¿ for the availability classifier of satellite images, which accelerates the learning speed, solves the problem of being trapped in the local minimum and improves the learning performance of fuzzy neural network. Using 122 satellite images, we compare the recognition results of the availability classifier trained by FNNBIFL or the traditional BP algorithm. Those results show that the recognition errors of FNNBIFL are reduced by 5.1%, and its learning speed is improved by 55%.
Vortex wakes generated by robins Erithacus rubecula during free flight in a wind tunnel

The wakes of two individual robins were measured in digital particle image velocimetry (DPIV) experiments conducted in the Lund wind tunnel. Wake measurements were compared with each other, and with previous studies in the same facility. There was no significant individual variation in any of the measured quantities. Qualitatively, the wake structure and its gradual variation with flight speed were exactly as previously measured for the thrush nightingale. A procedure that accounts for the disparate sources of circulation spread over the complex wake structure nevertheless can account for the vertical momentum flux required to support the weight, and an example calculation is given for estimating drag from the components of horizontal momentum flux (whose net value is zero). The measured circulations of the largest structures in the wake can be predicted quite well by simple models, and expressions are given to predict these and other measurable quantities in future bird flight experiments.

AIM Development of functionalized nanocomposites containing AgNPs-PVP-Glucantime® to evaluate their leishmanicidal activity as a novel method for improving the pharmacological properties of the drug Glucantime® against extracellular promastigotes and intracellular amastigotes of Leishmania amazonensis in vitro to treat cutaneous leishmaniasis. MATERIALS & METHODS The silver nanoparticles and nanocomposites prepared containing silver nanoparticles, polyvinylpyrrolidone and different amounts of Glucantime were characterized using transmission electron microscopy, x-ray diffraction, energy-dispersive x-ray spectroscopy and ζ potential analysis; in addition, the in vitro cytotoxicity was evaluated. RESULTS The nanocomposites showed an inhibitory effect on the cellular viability of promastigote forms, with values of 47.06, 51.71 and 65.67% for nanocomposite1, nanocomposite2 and nanocomposite3, respectively, as well as a dose-dependent decrease in the infectivity index, with values of 33.33 and 23% for nanocomposite2 and nanocomposite3, respectively. CONCLUSION The proposed nanocomposite reveals leishmanial activity and the absence of cytotoxicity in macrophages. Further investigations will be conducted in vivo.
The impact of work related variables on librarians' organizational commitment and job satisfaction

This study attempted to assess the impact of five (5) work related variables (role conflict, role clarity, job autonomy, job performance feedback and job involvement) on organizational commitment and job satisfaction among Malaysian university librarians. The study sought to address the following research questions: (a) do work related variables such as role conflict, role clarity, job autonomy, job performance feedback and job involvement correlate significantly as well as significantly predict the variation in organizational commitment and job satisfaction among university librarians in Malaysia; and (b) does this set of five (5) work related variables have a greater/lesser impact on organizational commitment as compared to job satisfaction or vice versa. A proportionate stratified random sampling technique was employed and questionnaires were distributed to 222 respondents comprising mainly of professionally trained library employees. A response rate of 63% was achieved resulting in 139 usable questionnaires that were returned. The findings of this study were based on the analysis of 139 usable questionnaires that were returned. The findings revealed that of the five (5) work related variables that were employed, all were found to be correlates of organizational commitment. Of these five correlates however, only three (3) were found to have statistically significant predictive relationship with organizational commitment: role clarity, job autonomy and job involvement Collectively these three (3) predictors account for 31.8% of the variance in organizational commitment. Of the five (5) work related variables that were employed to examine their relationship with job satisfaction, only four were found to correlate significantly with job satisfaction: role conflict, role clarity, job autonomy and job performance feedback. Of these 4 work correlates, only two (2) were found to significantly predict the variation in job satisfaction. Collectively these two variables (role conflict and role clarity) account for 16.3% of the variance in job satisfaction. Hence, the impact of work related variables was greater for organizational commitment (31.8% of the variance) than for job satisfaction (16.3% of the variance). Only role clarity was found to be a significant correlate as well as a significant predictor of organizational commitment as well as job satisfaction.
Song Processing in the Zebra Finch Auditory Forebrain Reflects Asymmetric Sensitivity to Temporal and Spectral Structure

Despite being commonly referenced throughout neuroscientific research on songbirds, reports of hemispheric specialization in the processing of song remain controversial. The notion of such asymmetries in songbirds is further complicated by evidence that both cerebral hemispheres in humans may be specialized for different aspects of speech perception. Some studies suggest that the auditory neural substrates in the left and right hemispheres of humans process temporal and spectral elements within speech sounds, respectively. To determine whether songbirds process their conspecific songs in such a complementary, bilateral manner, we performed functional magnetic resonance imaging (fMRI) on 15 isoflurane anesthetized adult male zebra finches (Taeniopygia guttata) while presenting them with (1) non-manipulated, (2) spectrally-filtered (reduced spectral structure), and (3) temporally-filtered (reduced temporal structure) conspecific song. Our results revealed sensitivity of both primary (Field L) and secondary (caudomedial nidopallium, NCM) auditory regions to changes in spectral and temporal structure of song. On the one hand, temporally-filtered song elicited a bilateral decrease in neural responses compared to the other stimulus types. On the other hand, spectrally filtered song elicited significantly greater responses in left Field L and NCM than temporally filtered or non-manipulated song while concurrently reducing the response relative to non-manipulated song in the right auditory forebrain. The latter hemispheric difference in sensitivity to manipulations of spectral structure in song, suggests that there is an asymmetry in spectral and temporal domain processing in the zebra finch auditory forebrain bearing some resemblance to what has been observed in human auditory cortex.
INSTITUTIONALIZATION AND EMOTIONAL LABOUR BEHAVIOUR: A RESEARCH IN HOSPITALITY ORGANIZATIONS

ABSTRACT Increasing competition and globalization make obligatory businesses to go toward differentiation. In competitive environment, that businesses institutionalize and make efforts of the different product and service toward customers enables them to proceed one step further than their competitors. It is considered that expecting the behavior of emotional labor, defined as emotional expression exhibited together with service from the employees, whose institutionalization perception are weak, will not be meaningful. With moving from here, in literature review carried out, any study has not been met about the effect of institutionalization perception on emotional labor behavior. Hence, in this study, an answer is searched for the main question “Does institutionalization perception affect emotional labor behaviors? ” . In the study, it aimed to study how institutionalization perception has an effect on emotional labor behaviors. The main hypothesis of the study is: H 1 = Institutionalization perception of employees affect their emotional labor behaviors in positive direction. The study has a quality of empirical research. In the study, survey technique is used as data collecting instrument. The universe of the study consists of accommodation businesses being in active. In the study, a valid feedback was obtained from 420 workers. The data obtained in this study will be analyzed by the method of simple linear regression methods. It is considered that the findings to be obtained at the end of the study will make contribution to eliminating the deficiency in the area and will present useful opinions toward the literature and application.
