Administrative scope: A foundation for role-based administrative models

We introduce the concept of administrative scope in a role hierarchy and demonstrate that it can be used as a basis for role-based administration. We then develop a family of models for role hierarchy administration (RHA) employing administrative scope as the central concept. We then extend RHA4, the most complex model in the family, to a complete, decentralized model for role-based administration. We show that SARBAC, the resulting role-based administrative model, has significant practical and theoretical advantages over ARBAC97. We also discuss how administrative scope might be applied to the administration of general hierarchical structures, how our model can be used to reduce inheritance in the role hierarchy, and how it can be configured to support discretionary access control features.
The Ladder of Success in Imperial China: Aspects of Social Mobility, 1368-1911

consist of six main sections: (1) editions, (2) prosody, (3) rhyme, (4) criticism, (5) history, (6) music. The first section will be further divided into (i) editions of separate authors (pieh-chi) and (ii) editions of anthologies and collected editions (tsung-chi). This 350-page book is therefore only the first half of the first subdivision of the first section of the whole work. Basically this book is an annotated bibliography in which the title of each collection is followed by the name, dates, and biography of the author, and by information about its contents and its various editions. The sources of all the information given are usefully listed at the end of each entry. The book's coverage is, however, much fuller than this account of it would suggest, since Professor Jao, in the course of conveying information of a more narrowly bibliographical kind, incidentally deals with many wider problems. For example, after the very first entry (Wen T'ing-yiin's Chin ch'iian tz'u), some nine pages are devoted to a discussion of tz'u-like developments preceding Wen T'ing-yiin, in which a wide range of problems is dealt with in a summary of masterly succinctness and clarity. This is characteristic of the whole book. Western contributions, for example (Baxter, Hoffmann), are not overlooked and are not merely noted, but carefully discussed and assessed. Professor Jao says in his introduction that this work grew out of his contributions to Ch'uan Ch'ing tz'u ch'ao and his entry on tz'u in the Ch'ao-chou gazetteer. He has been engaged on it now for something like 20 years. When the whole has been published it will be possibly the most important reference work in the field of Chinese literature to be produced in our time. The inclusion of prefaces by such internationally distinguished scholars as Professor Demieville and Professor Yoshikawa Kojiro bears eloquent testimony to this fact. It is unfortunate that the index of so important a book should contain a large number of printer's errors. I append a list for the use of those who already possess a copy and in the hope that they will be corrected in the book's next impression.
Warfarin reversal

Warfarin is the most commonly used oral anticoagulant in the UK. It is associated with few side effects apart from haemorrhage. The most appropriate way to reverse the anticoagulant effect of warfarin depends on the clinical circumstances. In serious bleeding, rapid reversal is required, whereas in minor bleeding or asymptomatic over anticoagulation, a more leisurely approach is usually appropriate. This review discusses the current approaches to warfarin reversal in clinical practice. The development of a uniform approach to warfarin reversal in the Northern Region is described.
Extracting Causal Knowledge from a Medical Database Using Graphical Patterns

This paper reports the first part of a project that aims to develop a knowledge extraction and knowledge discovery system that extracts causal knowledge from textual databases. In this initial study, we develop a method to identify and extract cause-effect information that is explicitly expressed in medical abstracts in the Medline database. A set of graphical patterns were constructed that indicate the presence of a causal relation in sentences, and which part of the sentence represents the cause and which part represents the effect. The patterns are matched with the syntactic parse trees of sentences, and the parts of the parse tree that match with the slots in the patterns are extracted as the cause or the effect.
The Effect of the Availability of a Dynamic Model on the Acquisition of a Complex Cyclical Action

This study examines the effect of the availability of a dynamic model on the acquisition of a complex cyclical action: slalom-type ski movements on a ski-simulator. A two-condition design was used, with N = 20 subjects per condition. In the experimental condition subjects had, during training trials, the benefit of the availability of a dynamic (video) model of an expert performer, while subjects in the control condition were left entirely to “discovery learning”. The dependent variables were the amplitude, frequency and fluency of the movement of the ski-simulator platform on which subjects were required to stand in operating the simulator. Movement characteristics of the platform were recorded by means of a microcomputer (Apple II+) coupled to a Selcom 403 camera (SELSPOT system). Subjects having the benefit of a dynamic model during training were shown, at the end of the five-day training period, to produce more fluent movements (of the platform) and to show greater consistency of fluency and of tempo than subjects left entirely to discovery learning. The results are discussed in the context of theories of perception and of motor learning.
Statins intake and risk of liver cancer

Abstract Previous studies have indicated that statins intake was associated with liver cancer risk, but presented controversial results. Studies in PubMed and EMBASE were searched update to February 2017 to identify and quantify the potential dose–response association between statins intake and liver cancer. Six eligible studies involving a total of 11,8961 participants with 9530 incident cases were included in this meta-analysis. Statistically significant association was observed between increasing statins intake and liver cancer risk reduction (OR = 0.46, 95%CI: 0.24–0.68, P <.001). Furthermore, the summary relative risk of liver cancer for an increase of 50 cumulative defined daily dose per year was 0.86 (95%CI: 0.81–0.90, P <.001). Evidence of a nonlinear dose–response relationship between statins intake and liver cancer risk was found (P for nonlinearity <.01). Subgroups analysis indicated that statins intake was associated with a significantly risk of liver cancer risk reduction in Asia (OR = 0.44, 95%CI: 0.11–0.77, P <.001) and Caucasian (OR = 0.49, 95%CI: 0.36–0.61, P <.001). Subgroup meta-analyses in study design, study quality, number of participants, and number of cases showed consistency with the primary findings. Additional statins intake is associated with liver cancer risk reduction.
ASYMPTOTIC BEHAVIOUR OF SOLUTIONS OF LUBRICATION PROBLEM IN A THIN DOMAIN WITH A ROUGH BOUNDARY AND TRESCA FLUID-SOLID INTERFACE

We study the asymptotic behavior of the solution of a Stokes flow in a thin domain, with a thickness of order ε, and a rough surface. The roughness is defined by a quasi-periodic function with period ε. We suppose that the flow is subject to a Tresca fluid-solid interface condition. We prove a new result on the lower-semicontinuity for the two-scale convergence, which allows us to obtain rigorously the limit problem and to establish the uniqueness of its solution.
The experience of sexual desire: Psychological correlates in a college sample

In order to elaborate on available models of sexual desire, we administered a sexual desire questionnaire to 144 college students, ages 18 to 54. Included in this measure were questions concerning the frequency of sexual desire, whether the respondent had participated in sexual activity without desire, or vice versa, experienced desire without sexual behavior, and a question assessing which cues are used by the subject to gauge sexual desire (e.g., frequency of intercourse, sexual dreams). Subjects also completed the Passionate Love Scale, Sexual Arousal Inventory, and Crowne‐Marlowe Social Desirability Scale. The results indicate that as a group, males report experiencing sexual desire more frequently than females. Males appeared to rely on similar indicators of desire as females, specifically genital arousal and sexual daydreams. For both males and females, sexual desire was significantly correlated with sexual arousal (r = 0.50, females; r = 0.44, males) while the correlation of desire and love was non.
Multi Home Transfer Learning for Resident Activity Discovery and Recognition

Activity discovery and recognition can provide unprecedented opportunities for health monitoring, automation, energy efficiency and security. Despite all the potential benefits, in practice we are faced with the main challenge of collecting huge amounts of data for each new physical space in order to carry out the conventional activity discovery algorithms. This results in a prolonged installation in the real world. More importantly, if we ignore what has been learned in previous spaces, we face redundant computational effort and time investment and we miss the insights gained from past experience that can improve the recognition accuracy. To overcome this problem, we propose a method of transferring the knowledge of learned activities from multiple source physical spaces, e.g. home A and B, to a target physical space, e.g. home C. Our method called Multi Home Transfer Learning (MHTL) is based on a location mining method for target activity discovery, a semi-Em framework for activity mapping, and an ensemble method for label assignment. In this paper we introduce the MHTL methodology. To validate our algorithms, we use the data collected in several smart apartments with different physical layouts.
Antioxidant responses and plasma biochemical characteristics in the freshwater rainbow trout, Oncorhynchus mykiss, after acute exposure to the fungicide propiconazole

In this study, the toxic effects of PCZ, a triazole fungicide present in aquatic environment, were studied in rainbow trout, Oncorhynchus mykiss, by an acute toxicity test. Compared to the control group, fish exposed to PCZ (96-h-LC50 , 5.04 mg/l) showed significantly higher ( P 0.05). The oxidative stress indices (levels of LPO and CP) of brain and muscle in the experimental group were higher compared to the control group, especially for a significant change ( < 0.05) in the brain. SOD, CAT, GPx and GR activity in the brain of experimental groups was significantly lower ( P < 0.05), however, an opposite tendency was found out in muscle. In addition, there are significant correlations between TBARS and CAT, TBARS and GPx, CP, and CAT, GR, and GPx in the fish brain. Thus, PCZ exposure changed the oxidative stress indices and plasma characteristics, and these changes may be used as potential bioindicators of the exposure and effect of PCZ in the control - led experiment. The use in monitoring of PCZ exposure under natural field conditions is possible, but it needs further investigations.
More conservative go/no-go response criterion under high working memory load

Previous work has shown that the efficiency of selective attention depends on the availability of cognitive control functions, including working memory. Here we examined the role of working memory in another task involving executive control, namely, a go/no-go task. Participants performed the Sustained Attention to Response Task, which requires withholding a prepotent response to an infrequent target, when at the same time placing a low or high load on an unrelated working memory task. Working memory load had the effect of reducing accuracy on the go trials, when at the same time increasing accuracy on the no-go trials. We interpret these findings to suggest that high working memory load led to a shift to a more conservative response criterion.
The Maximum Block Size of Critical Random Graphs

Let $G(n,\, M)$ be the uniform random graph with $n$ vertices and $M$ edges. Let $B_n$ be the maximum block-size of $G(n,\, M)$ or the maximum size of its maximal $2$-connected induced subgraphs. We determine the expectation of $B_n$ near the critical point $M=n/2$. As $n-2M \gg n^{2/3}$, we find a constant $c_1$ such that \[ c_1 = \lim_{n \rightarrow \infty} \left(1 - \frac{2M}{n} \right) \, E B_n \, . \] Inside the window of transition of $G(n,\, M)$ with $M=\frac{n}{2}(1+\lambda n^{-1/3})$, where $\lambda$ is any real number, we find an exact analytic expression for \[ c_2(\lambda) = \lim_{n \rightarrow \infty} \frac{E B_n} {n^{1/3}} \, . \] This study relies on the symbolic method and analytic tools coming from generating function theory which enable us to describe the evolution of $n^{-1/3} \, E B_n $ as a function of $\lambda$.
Theoretical notes on the sociological analysis of school reform networks

Nearly two decades ago, Ladwig outlined the theoretical and methodological implications of Bourdieu’s concept of the social field for sociological analyses of educational policy and school reform. The current analysis extends this work to consider the sociological import of one of the most ubiquitous forms of educational reform found around the planet: school reform networks. On the one hand, this analysis highlights the extent to which schooling is composed of multiple, co-existing social fields, which offer school reform networks ample leverage points for change. On the other hand, the degree to which reform networks hope to realise their ambitions fundamentally depends on their capacity to leverage the transferability of capitals among those social fields that govern the daily practices of schooling.
Clinical and Echographic Features of Retinochoroidal and Optic Nerve Colobomas.

PURPOSE We reported the clinical and echographic features of colobomas, prevalence of retinal detachment, and associated visual acuity in these patients. METHODS The study is a nonrandomized consecutive case series of 140 colobomatous eyes in 98 patients (age range, 0-83 years). Coloboma depth, width, volume, and relative coloboma excavation (coloboma depth/axial length) were measured using standardized echographic images. The presence of structural and other ocular abnormalities was noted. The clinical and echographic findings present were correlated with visual acuity of the patient. In addition, these features were correlated with the presence or absence of retinal detachment. RESULTS Increased relative coloboma excavation was significantly associated with an increased risk of retinal detachment. A relative coloboma excavation (ratio of coloboma depth to axial length) greater than 0.15 was associated with an increased risk of retinal detachment (52%), compared to those with a relative coloboma excavation less than 0.15 (23%, P = 0.014). The presence of any structural abnormality and the presence of a retrobulbar cyst were associated with increased risk of retinal detachment and severe visual impairment (worse than 20/200). Increased coloboma depth, width, volume, and relative coloboma excavation were not associated with increased risk of severe visual impairment. CONCLUSIONS Clinical and echographic features of colobomas may be used in predicting the risk of retinal detachment. Measuring relative coloboma excavation upon presentation may alter follow-up and assist in the diagnosis of retinal detachment.
Analysis and Optimization of UB Video's H.264 Baseline Encoder Implementation on Texas Instruments' TMS320DM642 DSP

The high coding efficiency enabled by the H.264 standard comes with substantially greater algorithmic complexity as compared to that of existing standards. This additional complexity complicates very much the implementation and optimization tasks. However, efficient implementations on different platforms exist that achieve real-time constraints in several video applications. One such good example is UB video's implementation of an H.264 Baseline encoder on the Texas Instruments' TMS320DM642 (DM642) digital signal processor, which can achieve good speed-quality trade-offs in video conferencing applications. In this work, we analyze and optimize UB video's implementation of its H.264 baseline encoder on the DM642. As a result, we have been able to improve memory transfer efficiency and reduce execution time, reducing the total number of encoder cycles by 18% without any loss in video quality.
Using tagged images of low visual ambiguity to boost the learning efficiency of object detectors

Motivated by the abundant availability of user-generated multimedia content, a data augmentation approach that enhances an initial manually labelled training set with regions from user tagged images is presented. Initially, object detection classifiers are trained using a small number of manually labelled regions as the training set. Then, a set of positive regions is automatically selected from a large number of loosely tagged images, pre-segmented by an automatic segmentation algorithm, to enhance the initial training set. In order to overcome the noisy nature of user tagged images and the lack of information about the pixel level annotations, the main contribution of this work is the introduction of the visual ambiguity term. Visual ambiguity is caused by the visual similarity of semantically dissimilar concepts with respect to the employed visual representation and analysis system (i.e. segmentation, feature space, classifier) and, in this work, is modelled so that the images where ambiguous concepts co-exist are penalized. Preliminary experimental results show that the employment of visual ambiguity guides the selection process away from the ambiguous images and, as a result, allows for better separation between the targeted true positive and the undesired negative regions.
SPOC1 modulates DNA repair by regulating key determinants of chromatin compaction and DNA damage response

Survival time-associated plant homeodomain (PHD) finger protein in Ovarian Cancer 1 (SPOC1, also known as PHF13) is known to modulate chromatin structure and is essential for testicular stem-cell differentiation. Here we show that SPOC1 is recruited to DNA double-strand breaks (DSBs) in an ATM-dependent manner. Moreover, SPOC1 localizes at endogenous repair foci, including OPT domains and accumulates at large DSB repair foci characteristic for delayed repair at heterochromatic sites. SPOC1 depletion enhances the kinetics of ionizing radiation-induced foci (IRIF) formation after γ-irradiation (γ-IR), non-homologous end-joining (NHEJ) repair activity, and cellular radioresistance, but impairs homologous recombination (HR) repair. Conversely, SPOC1 overexpression delays IRIF formation and γH2AX expansion, reduces NHEJ repair activity and enhances cellular radiosensitivity. SPOC1 mediates dose-dependent changes in chromatin association of DNA compaction factors KAP-1, HP1-α and H3K9 methyltransferases (KMT) GLP, G9A and SETDB1. In addition, SPOC1 interacts with KAP-1 and H3K9 KMTs, inhibits KAP-1 phosphorylation and enhances H3K9 trimethylation. These findings provide the first evidence for a function of SPOC1 in DNA damage response (DDR) and repair. SPOC1 acts as a modulator of repair kinetics and choice of pathways. This involves its dose-dependent effects on DNA damage sensors, repair mediators and key regulators of chromatin structure.
Joint estimation of activity signal and HRF in fMRI using fused LASSO

In this paper, we propose a novel voxel-based method for joint estimation of underlying activity signal and hemodynamic response function (HRF) in functional magnetic resonance imaging (fMRI). In the proposed two stage iterative framework, fused-least absolute shrinkage and selection operator (Fused LASSO) penalty is utilized for activity detection and HRF estimation. Conditions of smoothness and sparsity are imposed on HRF for its estimation. The validity of the proposed method is demonstrated on both synthetic and real fMRI data.
Progress in the Clinical Management of Haemophilia

In recent years, for obvious reasons, the clinical management of haemophilia has been overshadowed, at least for those closely involved, by problems related to the human immunodeficiency virus (HIV) and the hepatidides. However, it is not the intention of this paper to describe the clinical management of the acquired immunodeficiency syndrome (AIDS) or new treatments for he­ patitis B and hepatitis C. It is more the intention to survey the current status, new developments and future directions of treat­ ment designed to correct the haemophilic defects. Nevertheless, the development of these treatments has been very much in­ fluenced by the problems of viral contamination of blood pro­ ducts and to a lesser but significant extent by the possible immunosuppressive effect of protein or other impurities. This it is claimed could aggravate the immune deficiency induced by HIV and accelerate the development of symptomatic AIDS. To put present therapeutic products and future possibilities into perspective it is useful to review briefly the development of specific factor concentrates (1). Citrate as an anticoagulant for blood transfusion was developed during the first world war and enabled the preparation of plasma. The identification of a specific anti-haemophilic factor during the late 1930's led to the rational use of fresh frozen plasma. The second world war was a boost to plasma fractionation. Primitive but very effective freeze dried factor VIII concentrates were developed in the post-war years using Cohn alcohol or the Keckwick-Wolf ether fractiona­ tion processes but haemophilia therapy was revolutionised by the development of the closed-bag cryoprecipitate process. Cryoprecipitate was not only used on its own as a single donor product, but also formed the starting point for the preparation of largepool freeze dried "intermediate" purity concentrates that formed the backbone of therapy during the late seventies and for much of the eighties albeit with the serious viral complications already mentioned.
